Faith is increased by drawing closer to God through prayer and the study of His Word, the Bible. Please note that we are not saved by works or by keeping the ten commandments. The bible says, “For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast” (Ephesians 2:8-9). Paul clearly understood and wrote that no one could earn salvation and that faith itself is a gift from God. Yet in the very next verse he went on to say that we are God’s “workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them” (verse 10).
Like James, Paul knew living faith would be accompanied by service and obedience to God and His laws. Paul wrote in Romans 3:31 “Do we then make void the law through faith? Certainly not! On the contrary, we establish the law.”
