ere did you find this "Becoming like Christ is a life long process called sanctification."
Rom 8:13 for if you are living according to the flesh, you must die; but if by the Spirit you are putting to death the deeds of the body, you will live.
We need to be putting the body to death, but it doesn't happen immediately.
1 Pet 1:14 As obedient children, do not be conformed to the former lusts which were yours in your ignorance,
We can go back and conform to our old way if we choose to.
Matt 26:41 "Keep watching and praying that you may not enter into temptation; the spirit is willing, but the flesh is weak."
How can we be tempted if the flesh is dead?
1 Cor 9:27 but I discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified.
We should practice discipline, it isnt already perfect.
1 Tim 4:7 But have nothing to do with worldly fables fit only for old women. On the other hand, discipline yourself for the purpose of godliness;
Rom 12:2 And do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what the will of God is, that which is good and acceptable and perfect.
The continual renewing is what transforms us, this is an on-going process.
Jas 1:2 Consider it all joy, my brethren, when you encounter various trials,
Jas 1:3 knowing that the testing of your faith produces endurance.
Jas 1:4 And let endurance have its perfect result, so that you may be perfect and complete, lacking in nothing.
Without testing and endurance, we can not become perfect.
Php 3:12 Not that I have already obtained it or have already become perfect, but I press on so that I may lay hold of that for which also I was laid hold of by Christ Jesus.
Php 3:13 Brethren, I do not regard myself as having laid hold of it yet; but one thing I do: forgetting what lies behind and reaching forward to what lies ahead,
Paul did not consider himself as already being perfect.
Heb 12:7 It is for discipline that you endure; God deals with you as with sons; for what son is there whom his father does not discipline?
Why would we need discipline if we are already perfect?
Luke 9:23 And He was saying to them all, "If anyone wishes to come after Me, he must deny himself, and take up his cross daily and follow Me.
Why does Jesus say to do this "daily" instead of just once if our flesh is already dead?
