So a person can accept Jesus as their personal savior and then a year later start cheating on his wife, smoking pot, searching for women online, go to strip clubs, beat his wife, ext. ext..
Unfortunately that is exactly what can happen, and many times does happen, because a person is not discipled. If you don't teach babies to do right and what is right they do not have to be taught to do wrong and will do wrong.
We forget that when a person becomes a Christian they are a baby and must be taught, nutured, developed, discipled. If that doesn't happen then you are going to have a messed up Christian, not a non-Christian. Just because they are not discipled properly and return to their former lifestyle doesn't negate their faith in the substitutionary death and shed blood of Jesus Christ, the Lamb of God on their behalf.
Again this is a one-time event, not a linear event.
and most of you feell that he wouldnt have to repent for all those sins!!!
Absolutely he would have to repent of those sins. If not there are severe consequences! This exposes the false teaching of some in Christendom that every saved individual is okay and God will not judge them or condemn them after they have been saved. God WILL NOT be mocked. If you sow to the flesh as a saved individual you WILL reap corruption.
Thank our AWESOME God though that if we die to self and sow to the Spirit we will reap LIFE!
Repentance comes after salvation and deals with our walk with the Spirit.
