Colossians 1:29
Whereunto I also labor, striving according to His working, which worketh in me mightily.
The Apostle Paul was a tireless servant of Christ. His purpose in life was to preach, to warn and to teach every man in all wisdom (verse 28). His desire was to present every man perfect in Christ Jesus (verse 28). He never forsook his mission, and he was subjected to many hardships because of it.
