"Teach us then to number our days

That we may gain a heart of wisdom." ~ Psalms 90:12

"O Jehovah, cause me to know my end,

And the measure of my days, what it is.

May I know how transient I am." ~ Psalms 39:4

"But what things were gains to me, these I have counted as loss on account of Christ. But moreover I also count all things to be loss on account of the excellency of the knowledge of Christ Jesus my Lord, on account of whom I have suffered the loss of all things and count them as refuse that I may gain Christ And be found in Him, not having my own righteousness which is out of the law, but that which is through faith in Christ, the righteousness which is out of God and based on faith, To know Him and the power of His resurrection and the fellowship of His sufferings, being conformed to His death, If perhaps I may attain to the out-resurrection from the dead." ~ Philippians 3:7-11.
