Saved/justified/sealed has nothing to do with believer performance.What you don't seem to understand is that while yes of course, we are saved by grace thru faith in Jesus- that faith causes a regeneration to take place within the believer- a gift from God- a new creation is born- being born of the Spirit- we no longer are under the dominion of sin like we once were. Sin has lost it's power over us. Before we did as we pleased and did not care. Now we are new and made new inwardly and because we now love God because He first loved us- we want to live in a way that is pleasing to Him. We are now able to put the deeds of our sinful flesh to death by the Spirit. - we now are to walk in the Spirit. This is very real! Read and understand
Romans chapter 6-
A believer who denies that reality may want to test himself to see if he is really in the faith. Is Christ in you? have you partaken of His Spirit?
Do you still live according to your flesh? Or do you see yourself rejecting sin and you have lost the desire to sin like you once lived,,? Do you know that the Lord is helping you now? Are you aware of His presence?
Do we slip up on occasion? Yes but it is not intentional but it happens. And we feel horrible when we slip up. It is usually in thought or word. We confess it and are forgiven in the blood of Jesus- we have confidence in his sacrifice for all time-, we don't want to sin.-
We no longer walk in sin..
It is a battle of flesh v Spirit-
but we have the full armour of God. -
Ephesians 6:10-18
"Finally, be strong in the Lord and in His mighty power. Put on the full armor of God, so that you can make your stand against the devil’s schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this world’s darkness, and against the spiritual forces of evil in the heavenly realms. Therefore take up the full armor of God, so that when the day of evil comes, you will be able to stand your ground, and having done everything, to stand. Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness arrayed, and with your feet fitted with the readiness of the gospel of peace. In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. And take the helmet of salvation and the sword of the Spirit, which is the word of God. Pray in the Spirit at all times, with every kind of prayer and petition. To this end, stay alert with all perseverance in your prayers for all the saints."
I hope you comprehend this post. I can't get much clearer than this. Most believers just understand since they also live it.
List JUST the verses from Paul that you believe teach otherwise
