Why are you moving your goal posts? You are being exposed, tread lightly. You said;
I know because Paul tells us, and I showed you. When you acknowledge this and offer a counter point of some sort, such as saying Paul is false, just let me know.
I'll explain salvation if you don't understand as soon as you say "Oh, I see". Other choices are as stated, you don't believe Paul, or you did know and wanted to conceal it.
Don't believe Paul? Of course I believe Paul, he's a strong man of God! I was only wondering how you know you are sealed by the Spirit, so far you've quoted the Bible, but I'm talking of your own experience?
Many say they are born of God, many quote the Bible, but how do they know? How do they know they are sealed by the Spirit? We should be experiencing the things that happened to those in the Bible in our own lives once we belong to God.
And it's not just because of what Paul tells us, or that it's written in the Bible, once we are born of God, the Spirit brings us from death to life, and our lives should be changed.
And with that comes the power of the Holy Spirit, and he seals our hearts, he closes the door so that Satan can't get in, and we are covered by the blood of Christ as his life grows within our hearts, sealing our hearts from the world and lusts of the flesh, we'll still be tempted, but as long as we keep our faith and walk in the Spirit, living by the will of God. Satan can't get in, because those born of God are sealed by the Spirit. This world should mean nothing to us, and I mean the lusts of it, not the natural beauty of the things God has created. I mean the works and lusts of it and the building up in it. As once we are sealed by the Spirit, we belong to God. And the only way that we fall away, is if we begin to lust after the flesh again. Jesus said of his apostles, that they were not of this world, as he wasn't of the world. Nor should we be once we are born of God.
When a submarine goes into the sea, the sea can't get in because it is sealed. And that's what it's like for those sealed by the Spirit, they are in the world, but not of the world. And the destroyer can't get in, just like in Exodus, because the blood of Christ is on the doorposts of our hearts, and I don't mean the crucifixion, but his life, his life in and through us, and we are strengthened by the Spirit of truth and life. And he that is in those born of God, is stronger than he that is in the world, and God won't let him touch them, he can't touch their heart or the life within, they are sealed by the Spirit. Unless they turn back and turn away from God again to lust after the flesh and this world, and like in Romans 1, he will turn them over their reprobate minds and they will be sealed no longer, because after knowing God, they have lusted after the flesh again after being saved from this world of sin and death, they turn back, foolishly looking to the world, lusting after it instead of trusting in God. They let the filth of the flesh back in.
So how do we know that we are sealed by the Spirit? Because those who are, are overcoming this world of flesh and sin, this world will mean nothing to them, and God will come first in their lives and Christ will be their rock, and they will be a living stone built upon the cornerstone, and his life will be in them and seen through them. And they will be living as Jesus taught them to, obeying God, living by his will, and they will continue in Gods goodness. Truly alive walking in the light, away from the death and darkness of this untoward world of sin!
So it's not just quoting what Paul, Peter or anyone else in the Bible said, it's a life experience, and the life in that is in those prophets, apostle's and disciples in the Bible, should be in those born of God too!
