“So teach us to number our days
that we may get a heart of wisdom.
Return, O Lord! How long?
Have pity on your servants!
Satisfy us in the morning with your steadfast love,
that we may rejoice and be glad all our days.
Make us glad for as many days as you have afflicted us,
and for as many years as we have seen evil.
Let your work be shown to your servants,
and your glorious power to their children.
Let the favor of the Lord our God be upon us,
and establish the work of our hands upon us;
yes, establish the work of our hands!” (Psalm 90:12–17 ESV)

“Look carefully then how you walk, not as unwise but as wise, making the best use of the time, because the days are evil. Therefore do not be foolish, but understand what the will of the Lord is” (Ephesians 5:15–17 ESV).

“Walk in wisdom toward outsiders, making the best use of the time. Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person” (Colossians 4:5–6 ESV).

“But do not overlook this one fact, beloved, that with the Lord one day is as a thousand years, and a thousand years as one day. The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance” (2 Peter 3:8–9 ESV).
