“To live by faith”
On one hand, Biblical Christianity is a “reasonable faith” about God’s active involvement in human history and his plan of human liberation in Jesus Christ to all who will trust in him for the forgiveness of their sins and salvation.
On the other hand, Biblical religion does not call followers of Jesus Christ to walk by reasonable faith, but to “live by (their) faith” in God. This is a call to think and live in the manner of Christ and to embody in the believer’s experience the patterns and character of his life.
The call to live by faith in God is a call to trust and a necessity for the believer’s daily decision and action to be grounded solely on God’s wisdom, guidance, and counsel. It is against the arrogance of this world and a human-centered life and ethics. To live by faith is to bodly affirm that God is the priority in all things.
“Trust in the Lord with all your heart
and lean not on your own understanding;
in all your ways submit to him,
and he will make your paths straight”
