“The new life in Christ, just like all natural life, must be nourished and strengthened. This is possible only in communion with Christ in the Holy Spirit and through the word of Scripture. Enlightened by the Spirit, believers gain a new knowledge of faith.
The gospel is the food of faith and must be known to be nourishment. Salvation that is not known and enjoyed is no salvation. God saves by causing Himself to be known and enjoyed in Christ.
Biblically speaking, faith is trust-filled surrender to God and His word of promise. In the New Testament, this trust involves acceptance of the apostolic witness concerning Christ and personal trust in Christ as Savior and risen, exalted Lord.”
