IF ORDINANCES AND COMMANDMENTS MUST BE OBEYED HOW ARE MANKIND SAVED BY GRACE, WHICH IS A FREE GIFT?

The Gospel plan is given through the grace of God. It is a gift to man. If man refuses to obey it he rejects the gift, which is the only means of his salvation.

"I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth." (Romans 1: 16).
