“Lord, you have been our dwelling place

throughout all generations.

Before the mountains were born

or you brought forth the whole world,

from everlasting to everlasting you are God” (Ps 90: 1 – 2),

My brain can’t get a grasp of what “everlasting to everlasting” means. People talk about eternity past and eternity future, but I find it impossible to imagine. All I know is that his infinity is one of the many ways God is vastly superior to me. To us.

“From everlasting”. Was there a beginning to God? The Scriptures don’t allow us to believe that. Somehow God has always been and always will be. And over that seemingly impossible span of time, he has always been in charge. He has always been God. He will always be God.

Before the mountains were born, before our planet spun on its axis, he has been the sovereign God. When people were created, he invited them to dwell with him. Even though many rejected the call, he held out his hand. Today, The Lord still holds out his hand.

Later, in Psalm 90 we read:

“Teach us to number our days,

that we may gain a heart of wisdom” (Ps 90: 12)

This is a stark reminder of the brevity of life on earth. God may be everlasting, but we are not here forever. Our souls will live on, but what will we do with the limited time we have before we die? Will we live intentionally, making the most of our time, loving God, and doing his will, or will we waste the opportunities set before us? Will we “number our days” -that is, put them to good use?

All human beings, like you and I have a paradoxical existence. We are temporal and we are eternal. We are not from everlasting, but eternity is laid out in before us. Faith in Christ will lead us to the dwelling place of God, but will we still number our days? Will we take seriously every minute, every day? Will we do everything we can to further his kingdom? Will we love the lost and feed the hungry? Will we carry out his will?

The psalmist (this is a prayer of Moses) believes that we will gain hearts of wisdom if we number our days. A finite life on earth lived with purpose, under the sovereignty of God, will feed the fertile soil where wisdom wants to grow.

Peter encouraged us to live with purpose, “For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge; and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness; and to godliness, mutual affection; and to mutual affection, love. For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ… make every effort to confirm your calling and election. For if you do these things, you will never stumble, and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ” (2 Peter 1: 5 – 11).

“After the death of Moses, the servant of the LORD, the LORD said to Joshua son of Nun, Moses’ aide: “Moses my servant is dead. Now then, you and all these people, get ready to cross the Jordan River into the land I am about to give to them —to the Israelites. I will give you every place where you set your foot, as I promised Moses. Your territory will extend from the desert to Lebanon, and from the great river, the Euphrates —all the Hittite country—to the Mediterranean Sea in the west. No one will be able to stand against you all the days of your life. As I was with Moses, so I will be with you; I will never leave you nor forsake you. Be strong and courageous, because you will lead these people to inherit the land I swore to their ancestors to give them” (Joshua 1: 1 – 6).

At the risk of taking verse five out of context, this has to be one of the most encouraging statements in the Bible: “I will never leave you nor forsake you”. “As I was with Moses, so I will be with you; I will never leave you nor forsake you.”

Joshua had seen firsthand the extraordinary relationship God had with Moses. “The LORD would speak to Moses face to face, as one speaks to a friend” (Ex 33: 11). Through Moses, The Lord had performed incredible miracles and executed deadly but righteous judgements. Moses had friendship with the almighty, sovereign God. God gave him the power to bring water out of a rock and part the Red Sea. And now Joshua is being told that The Lord will be with him in the same way.

I don’t know about you, but if I were Joshua, I would really struggle to get my head around the enormity of all that.

And yet, if we read our Bibles, as followers of Jesus, we have stepped into a not dissimilar relationship with God. We are told in Ephesians 2 that we are “raised us up with Christ and seated… with him in the heavenly realms in Christ Jesus” (Eph 2: 6). We are forgiven and cleansed from sin, we are adopted into his family, and we are now spiritually “in Christ”, where he is at the right hand of the Father.

Our prayers are not only heard, but we have been given authority to speak in his name, make disciples of all nations, heal the sick and cast out evil spirits. And to top it all, Jesus told his disciples (and therefore also us) “surely I am with you always, to the very end of the age.” (Matt 28: 20). In other words, I will never leave you nor forsake you.

The One was a friend to Moses and Father to the eternal Son, is with us and will never leave us or forsake us.

I don’t deserve it and nor do any of us! But we can live in the good of it and start using the authority he has given us to change our little corner of the world.

During a long speech that Moses gave to the people of Israel, after their 40-year trek in the wilderness and just prior to entering the Promised Land, he said this:

“Only be careful and watch yourselves closely so that you do not forget the things your eyes have seen or let them fade from your heart as long as you live. Teach them to your children and to their children after them. Remember the day you stood before the LORD your God at Horeb, when he said to me, “Assemble the people before me to hear my words so that they may learn to revere me as long as they live in the land and may teach them to their children.” You came near and stood at the foot of the mountain while it blazed with fire to the very heavens, with black clouds and deep darkness. Then the LORD spoke to you out of the fire. You heard the sound of words but saw no form; there was only a voice. He declared to you his covenant, the Ten Commandments, which he commanded you to follow and then wrote them on two stone tablets. And the LORD directed me at that time to teach you the decrees and laws you are to follow in the land that you are crossing the Jordan to possess” (Deut 4: 9 – 14).

Be careful. Watch yourselves closely. Don’t forget what you have seen and known. Keep them in your heart. Teach them to your kids and grandkids.

“Watch yourself” is an odd instruction and is probably more commonly used today as a warning against having an accident. “Watch yourself on that muddy slope”. “Watch yourself with that hot pan”. Today we hear it as a call to be careful.

Although Moses is speaking to the whole nation, he personalises it for every individual. He is calling every person to be careful. The fate of the nation depends on the choices of each person in it. So, watch yourself, he says, each and every one of you. Decide now what is important. Make intentional decisions today about what you will choose. Let those choices and behaviours directly relate to what you have seen the Lord do and what you have heard him say. Don’t forget any of his words and deeds.

In fact, people, you will likely have children one day, so make habits now to daily remember the Lord and fix them in your life. This will help you to pass them on effectively to the next generation. Your personal response to serve the Lord is vital. Remember: this is all bigger than any of us.

For his sake and his purposes, and for your influence upon those around you, watch yourselves closely.

Perhaps this is still a call to the church today. Watch yourself, each and every one of you. Decide now what is important. Make intentional decisions today about what you will choose. Let those choices and behaviours directly relate to what you have seen the Lord do and what you have heard him say. And don’t forget any of his words and deeds. For his sake and his purposes, and for your influence upon those around you, watch yourselves closely.

As Paul wrote to Timothy, “Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress. Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers” (1 Tim 4: 15 – 16).
