Foundation of Christion faith was given by revelation of the word of Jesus Christ by the HOLY SPIRIT. The word of God is the foundation of faith through which we must believe to receive his promises, salvation, healing, peace, and joy, for our lives, [eternal life for ever and ever]. For we walk by faith, not by sight. 2 cor. 5: 7, Living accord to the truth of God's word and the testimony of his spirit. Faith is in believing God's testimony and living in agreement with it.
