Faith that saves continues and is not some shallow, temporary belief that has no root, produces no fruit and withers away. Man is saved through faith and not by works (Romans 4:5-6; Ephesians 2:8,9; Titus 3:5; 2 Timothy 1:9); yet genuine faith is (evidenced) by works. (James 2:14-26)Yes, genuine faith produces or is followed/manifested by loving behavior (Gal. 5:22-23) or good deeds (Eph. 2:8-10),
persevering faith continues from first/conversion to last/death (Rom. 1:17, Matt. 10:22), and such non-meritorious faith
merely receives God's grace/salvation/HS (Rev. 3:20, 1Cor. 12:13).
*Jesus Christ saves us through faith based on the merits of His finished work of redemption "alone" and not based on the merits of our works. (Romans 3:24-28)
It is through faith "in Jesus Christ alone" (and not based on the merits of our works) that we are justified on account of Christ (Romans 4:5-6; 5:1; 5:9); yet the faith that justifies does not remain alone (unfruitful, barren) if it is genuine. (James 2:14-26) *Perfect Harmony*
