Psalm 144:4 Man is like to vanity: His days are as a shadow that passeth away.
We never ought to forget that our lives are short. We are here but for a moment. Life will be over before we know it. The Lord says our lives are like a vanity. Something empty. Something of no real value. He says our lives are like a shadow. It is here and it is soon gone.
So if I understand the truth I know that my earthly life will be short but my life will last forever somewhere. This life is very temporary. However we will be somewhere forever. We need to consider how much we need God. We need to trust Him and believe Him because we want to live forever with Him.
Life has no real purpose without the Lord. We want to seek Him. We want to find real meaning, real purpose, and even the life that we wish we had!
