Christ actually accomplished something. He brought us INTO life, INTO himself, INTO God. He has become our very life, for our life is found in HIS resurrection from the dead, not OURS. His resurrection IS our resurrection. His life IS our life.
Let me get very blunt. What kind of gospel leaves you in the unknown regarding the very premise of the actual good news of Christ, which is full confidence in one’s relationship to God through Christ? What kind of gospel causes you to think it’s all about what you do or don’t do, when the good news declares that it’s not about you at all but all about Christ and what he has done and is now doing? source
