Scriptures speak of at least two ages to come. Adam was removed from the tree of life lest he eat it. He was not immortal. Satan's power and authority to deceive. His mercy endures forever.
Mercy triumphs over judgment.
We know we are supposed to have it, even for our enemies, but we fall short without acknowledging it. Therefore, we become blind while saying we see. We find ourselves boasting about our righteousness not seeing we have become blind and naked. There is certainly much boasting in the church. This boasting will be dealt with when the Rock falls in judgment on His people.
