When you said “it is certainly worth your time to know the saving Gospel of Grace that can alone lead you to eternal life.” I would agree completely. But when you look at your statement there is an important word, “lead”.
Faith can lead you to Grace and Grace can lead you to that Eternal life.
Faith in The Christ as your Deliverer from the disease of sin results in immediate ‘born from above’. THEN His life indwells you to show the works of righteousness that He originates through you. Grace is not a reward fro diligence. To believe that is contrary to what God says in His Word. Sadly, that striving to obtain is the gospel of catholiciism but not eh Gospel of God’s Grace in Christ Jesus.
