A man in Christ is not the old man purified, nor the old man improved, nor the old man in a better humour, nor the old man with additions and subtractions, nor the old man dressed in new clothes but completely a new creation.
The new creation is not a development, or an outgrowth, but a creation. The new man/ woman is completely new; wired with huge potentials. Before you were saved, your spirit is dormant, “dead in sins and trespasses” Eph. 2:1. But when you believe in Jesus, His resurrection power electrifies your spirit to life, by coming into it. Paul said, “Even when we were dead in sins, has [He] quickened us together with Christ” Eph. 2:5. This is a fulfilment of Jesus’ words, “I am the resurrection, and the life: he that believes in Me, though he were dead, yet shall he live” Jn. 11:25. We were dead spiritually.
The New Creature in Christ (born-again, Spirit-indwelt human spirit) has powers, abilities, and resources he or she never had before. You can exercise the abilities of your Father as enshrined in Scripture. “These things & greater things shall you do…” (John 14:12) You have Christ in the inside of you and you know no defeat. You are now the greatest invention of God, full of potentials. Just say to yourself ‘I am powerful because of Christ’.
