There are two types of Christians and it is needed to make a choice. One group believes saved if go back to a life of sin, the other believes must overcome sin to make it. If the second group perseveres and believes to go to heaven, how will they make it without the power of the Holy Spirit?
One thing that will help is confessing and putting known sin under the blood. God has promised to give us grace and not a licence to sin. We need him to tell us where we are missing it. We could have hidden things that we don't know about. David said Lord keep me from secret faults.
It would be so easy to live the wrong life and have no conviction. That is called fire escape security. Nobody wants to go to Hades. God is holy and we must be so we can show ourselves worthy to escape judgment. We must go to the cross also and die to self love and gratification. God wants to bless us with abundant life---that must be a spiritual life---proof ----Rom. 8:6 to be fleshly minded is death but to be spiritually minded is life and peace.
