Faith.
Now faith is being sure of what we hope for and certain of what we do not see. This is what the ancients were commended for.
By faith we understand that the universe was formed at God's command, so that what is seen was not made out of what was visible.
By faith Abel offered God a better sacrifice than Cain did. By faith he was commended as a righteous man, when God spoke well of his offerings. And by faith he still speaks, even though he is dead.
By faith Enoch was taken from this life, so that he did not experience death; he could not be found, because God had taken him away. For before he was taken, he was commended as one who pleased God.
And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.
- Hebrews 11:1-6

How precious to me are your thoughts, O God!
How vast is the sum of them!
- Psalm 139:17

Whom have I in heaven but you?
And earth has nothing I desire besides you.
My flesh and my heart may fail, but God is the strength of my heart and my portion forever.
Those who are far from you will perish; you destroy all who are unfaithful to you.
But as for me, it is good to be near God.
I have made the Sovereign LORD my refuge;
I will tell of all your deeds.
- Psalm 73:25-28
