At some point we must decide that we no longer need to prove what kind of self-made man we are and show the world what kind of man God desires us to be. The Word refers to us as 'born again'. In other words "the emergence of a new individual from the body of its parent". The old man is history and the new man has emerged from a new parent.
Col 3:1-4
If then you were raised with Christ, seek those things which are above, where Christ is, sitting at the right hand of God. Set your mind on things above, not on things on the earth. For you died, and your life is hidden with Christ in God. When Christ who is our life appears, then you also will appear with Him in glory.
NKJV
We are now hidden in Christ and that is what makes us "Tougher Than Hell"
