Walk By Faith Not By Sight

Jesus said to him, "Have you believed because you have seen me? Blessed are those who have not seen and yet have believed." (John 20:29 ESV)
Though you have not seen him, you love him. Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, obtaining the outcome of your faith, the salvation of your souls. (1 Peter 1:8-9 ESV)

(For we walk by faith, not by sight:) (2 Corinthians 5:7 KJV)
