For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ. But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us.
2 Corinthians 4:6-7
My flesh and my heart faileth: but God is the strength of my heart, and my portion for ever.
God is our refuge and strength, a very present help in trouble.
