The hardest thing 最困難的事
“The hardest thing in the world for the Christians is to live by faith, rather than by sight.
“It’s difficult because we never see God. We have not been eyewitnesses of the Resurrection like the first century apostles were. We live on the basis of the testimony of those who went before us, and we are to walk by faith. Living Faith is trusting the promises of God. It’s one thing to believe in God, but it’s quite another thing to believe God.”
— R. C. Sproul
