Now, however, we have become children of God through faith in Christ (John 1:12). Consequently, it follows that without faith in Christ, no work is able to please God the Lord. The sum and substance of all good works consist of love (Rom. 13:8). But now upright, God-pleasing love sprouts forth out of faith, as it is written in Gal. 5:6—Faith is productive through love. Upright good works are fruits of the Spirit (Gal. 5:22). Now, the Holy Spirit is given into our hearts through faith in Christ (Gal. 4:6). Since you are God’s children, God sent the Spirit of His Son into your hearts. Through Him we cry out, Abba, dear Father. The good works are fruits of righteousness (Phi. 1:11). But we become righteous before God solely through faith in Christ (Rom. 3:28). Anyone who remains in Christ and Christ in him, the same person brings forth much fruit (John 15:5). However, now Christ resides in our hearts through faith (Eph. 3:17). (Schola Pietatus-Volume 1 by Johann Gerhard, Repristination Press, p. 15-16)
