2 Corinthians 4:10, always carrying about in the body the dying of the Lord Jesus, that the life of Jesus also may be manifested in our body.
Manifestation is taking notice of something that is beginning to show. Saints bless God, and his benefits for your life will manifest.
The manifestation of the mark of Christ in your life means that you are already dead to this world and the only thing that you live for is to serve the Lord. And the main purpose of serving God is to bless Him, no matter what the situation.
