Summary: This sermon deals with our need to live our lives intentionally for the Lord before it is too late.
Psalm 39:4-5, 90:12
We’re going to look at our need to reassess life, to life our lives intentionally given the fact we only have so many days to live upon this earth before eternity sets in.
This reality is what drove King David to live his life intentionally, realizing that the end of his life was only a single breath away.
“Show me, O Lord, my life's end and the number of my days; let me know how fleeting is my life.” (Psalm 39:4 NIV)
In the process of reassessing our lives, what we’ll find is that the things we consider to be important just might not be that important after all. To reassess our life, therefore, we need to ask ourselves, “Am I doing the most important thing?”
Why wait for our days to be numbered by someone or something else before we start doing what we should have been doing all along. It’s about getting our lives refocused, because we only go around once in this life.
Life is not cyclical but lineal. There are no mulligans or do-overs. Once it’s done, it’s done. Once this life is over, either heaven or hell are in our futures.
Think of it like this, right now we’re all going 66,000 miles an hour. That’s how fast this world is spinning on its axis. If you’d like to know how fast that is, it’s faster than the spin cycle on a washing machine.
But what if we had just a few more spins left, how would we live our lives, and what would we live our lives for? Would we make them count, or would we just waste them away?
King David understood how fleeting life was, which prompted him to go on and ask God to show him how long he had left.
“My life is no longer than the width of my hand. An entire lifetime is just a moment to you; human existence is but a breath.” (Psalm 39:5 NLT)
The Apostle James says that life is here one moment and then gone the next, that it’s like a puff of vaporized water. Poof, and its gone!
David understood just how fleeting life is, seeing that his life was under a death sentence issued by King Saul. Saul literally put a hit out on David, and as a result David lived life on the lamb dodging spears thrown in his direction.
All David knew is that God promised him a kingdom, but Saul wanted him dead before that kingdom could be realized. Therefore David asked God to help him know how to live his life under a death sentence.
Knowing that our days are numbered, how many of us will truly reassess our lives, and change how we live them? Yet even then we wait thinking, “Oh, nothing is going to happen to me.”
But rather than waiting until we hear the words, “You only have a week, a month, or a year left to live,” we should be seizing the day, seizing the time we have for what is truly important.
Psalm 90 is a prayer believed to be written by Moses. It says that life is like a whisper, or a sigh, and then it says that the average person will only live 70 to 80 years. With this knowledge Moses asks God to tell him how to live life accordingly.
The Psalm was probably written close to the end of Moses’ life, which was toward the end of their wilderness wanderings, which means that Moses would have witness and presided over all who died in the wilderness, and we’re talking about a whole lot of people, the whole adult population who rebelled against God when He first told them to cross the Jordan River.
Recognizing, therefore, the brevity of life, Moses asks God to give them the wisdom to know how to their live lives knowing that someday they were all going to die, and it might be the very next day.
In other words, “Lord, give us the wisdom and insight to know not when we’re going to die, but how we are to live in light of our mortality and then in light of our eternity?”
“Teach us to number our days aright, that we may gain a heart of wisdom.” (Psalm 90:12 NIV)
Why wait for someone or something else to number our days? Instead let’s live our lives according to God’s ways and no longer our own. This involves a choice where we take the initiative to live for God and His kingdom, or as Jesus taught us to pray, “Thy kingdom come. Thy will be done in earth, as it is in heaven.” (Matthew 6:10 KJV)
Why wait for someone else to tell us how long we have to live, or live life with uncertainly always fearing the unknown and what tomorrow may bring. Instead, let’s ask God to help us number our days rightly, and to give us the wisdom we need on how we are to live.
