If you are in Christ, you lose your rights. You are no longer your own. You are Christ’s procession. He owns you. He is your Master. How does that sit with you? Does your heart fight against statements like this? If you are honest with yourself, the answer is yes.
Our sinfulness screams for self-possession, not Christ-possession. Everyone accepts the Savior Jesus, but many people reject the Lord Jesus. Unfortunately, those two titles are inseparable. If God has redeemed you through Jesus Christ, you lose your identity. You are now a follower of Jesus, the old has gone and the new has come. You make a 180 turn and stop being zealous against God and start being zealous for God.
What I see in Titus 2:14 is that Jesus’ zeal to save us produces a zeal to serve Him. This verse supports that this transformation is a guarantee, it just happens. What I find interesting is that the word zealous is extremely strong. The Greek word is zēlōtēs. This means one that is burning with zeal, jealous of any rival to God, or most eagerly desirous. In this day in age, I would use the word radical.
I think we tend to forget that Jesus Christ was himself consumed by zeal (John 2:17, “"Zeal for your house will consume me.") and His zeal for God’s Glory was operating 24 hours a day. (John 5:17, “But Jesus answered them, "My Father is working until now, and I am working."). We forget that the this same Jesus that gave himself for you, now lives in you. His Spirit compels you to live a life in conformity to who He is. Galatians 2:20, “I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.”
The bottom line is that Christians are to look like Christ. Christ did not serve two masters, nor should you. We are possessed by Jesus Christ and are to radically follow him, no matter what the cost. If you are a Christian, unleash who you are in Christ Jesus and serve Him with a holy zeal.
