In the Garden of Eden, when Adam and Eve fell for the temptation of Satan, the outcome was as if Satan had infected them with his sinfulness, pridefulness, and selfishness. This virus was then passed onto Adam and Eve’s descendants.
Then, Jesus Christ died to the sin, pride, and self that had infected humanity. And by His death and our faith, we can participate in Jesus’ death and also be dead to the virus of sinfulness, pridefulness, and selfishness.
The best part about all this is that, with death to our sinful nature, we make room for the Spirit of Jesus to take its place so that we can say with Paul, “I no longer live, but Christ lives in me.”
