'By Faith' in the Bible

And on the basis of faith in His name, it is the name of Jesus which has strengthened this man whom you see and know; and the faith which comes through Him has given him this perfect health and complete wholeness in your presence.

and he asked for letters [of authority] from him to the synagogues at Damascus, so that if he found any men or women there belonging to the Way [believers, followers of Jesus the Messiah], men and women alike, he could arrest them and bring them bound [with chains] to Jerusalem.

and He made no distinction between us and them, cleansing their hearts by faith [in Jesus].

to open their [spiritual] eyes so that they may turn from darkness to light and from the power of Satan to God, that they may receive forgiveness and release from their sins and an inheritance among those who have been sanctified (set apart, made holy) by faith in Me.’
