It's true, there is another Satan among us, and he's worse than the true Satan. This other Satan is not the true Satan of Scripture. But, religions, including Christianity, promote this other Satan, causing many people to lose peace. Their peace is stolen as they are led to believe this other Satan can actually disrupt God's good plans for His creation. This other Satan, they say erroneously, does things that the Scriptures teach are the work of God alone. The Scriptures reveal the true God and the true Satan. Understanding the truth will bring you the peace of God in this wicked eon.
Jesus is greater than Adam? Yep. His death and resurrection overcome all the effects of Adam's sin. Adam's sin brought death to all mankind; Jesus' work causes all to have immortal life. Romans 5:18 - "Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men" (ESV). 1 Corinthians 15:22 - "For even as, in Adam, all are dying, thus also, in Christ, shall all be vivified" (Concordant Literal New Testament). Believe it!
