Romans 14:22-23 (New King James Version)
22 Do you have faith?[a] Have it to yourself before God. Happy is he who does not condemn himself in what he approves. 23 But he who doubts is condemned if he eats, because he does not eat from faith; for whatever is not from faith is sin.[b]
All things should be done in faith!
1 Peter 1:6,7— Our faith is often tested by affliction!
James 1:3 (New King James Version)
3 knowing that the testing of your faith produces patience.
At the point where hope would otherwise become hopelessness, it becomes faith. ~Robert Brault
