Obedience/love unto God is the evidence of the state of one’s heart/mind. This love is the fruit of the Spirit. It is the fruit produced from God living, dwelling in the mind/heart.
Thus, the fruit shows forth the faith that produces the good works of God. It is the evidence that one is saved: delivered from sin. It is evidence of salvation—not to receive salvation.
Obedience is evidence we already have received salvation from God. We could not and did not earn it. Salvation is God’s gift to those who are the called, who are the chosen of God. Period. Let that sink in.
