According to Jesus, Satan came to “steal, kill, and destroy.” Look at the way the world is and the way it has been since time immemorial. Most have been following the “prince of this world,” and that evil fruit should give you an idea of what the devil’s like. But Jesus, in His own words, came to “seek and save,” “to give life, and that more abundantly.” It is God’s purpose through Christ to reclaim this world from the prince of darkness, to restore and renew. That should give you an idea of what He’s like.
I think about Jesus’ baptism. Once the Spirit came down, Satan noticed a “disturbance in the Force, the presence of his former Master,” so to speak, and so he showed up rather quickly to check Jesus out and test Him. In the wilderness, the real battle had begun, one that would culminate at Calvary. Whereas the powers of this world sought to kill Him and make a public spectacle of Him, He “disarmed the powers and authorities. He made a public spectacle of them, triumphing over them by the cross” (Colossians 2:15). That should give you an idea of what Jesus was like.
