Those who hope in the Lord will renew their strength

But those who hope in the Lord
will renew their strength.
They will soar on wings like eagles;
they will run and not grow weary,
they will walk and not be faint.—Isaiah 40:31

Quietly wait on God, study his word, pray, worship and meditate on his love for you. He will restore you, re-energise you and empower you to face everything you need to do.

God works thing in our lives that we could never do for ourselves

“Answer this question: Does the God who lavishly provides you with his own presence, his Holy Spirit, working things in your lives you could never do for yourselves, does he do these things because of your strenuous moral striving or because you trust him to do them in you? Don’t these things happen among you just as they happened with Abraham? He believed God, and that act of belief was turned into a life that was right with God.”
Galatians 3:5-6 MSG
