Many believers are divided against each other over secondary issues and many believers have been offended by others and so they do not speak with each other. I for one will not step foot in a IFB church again for various reasons. So how will God reconcile believers in heaven? Will He wipe our bad memories? Or will we have them but just look at them differently? This is a tough question but as you know Christians are very divided against one another these days.
I think there are some issues with the question and assumption. First we are told this;
Mat 6:14,15
For if ye forgive men their trespasses, your heavenly Father will also forgive you:
But if ye forgive not men their trespasses, neither will your Father forgive your trespasses.
By that I am of the mind if we die in un-forgivness of another we are not forgiven.
The second thing is I think there is not nearly as many Christians as many think.
Mat 7:14
Because strait
is the gate, and narrow
is the way, which leadeth unto life, and FEW there be that find it.
Mat 7:21-23
Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.
Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?
And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
What I can tell you with some certainty is that there is NOT going to be any division in heaven. The real problem is being very sure we are going.
Now that being said I feel I need to explain how to get there.
Contrary to what some claim we do not get saved by asking Jesus into our hearts, praying a so called prayer of faith, accepting Him as our personal Savior, being baptized or confirmed, confessing our sin, or belonging to a church as the bible never teaches those things for salvation. Nor do we get saved by cleaning up our lives as that is works. Yes any or all of those things may make the church roles fat and the preacher feel or look good when we come forward, but they can also cause us one day to hear, I never knew you.
Salvation takes repentance toward God and faith in the Lord Jesus Christ, Acts 20:21. Make no mistake. We cannot be a friend of Christ while remaining a rebel against God. The word repent, from the Greek word metanoia, means a change of mind or direction. It is not 50%, 75% or 99%. It is 100%. God is not interested in us almost repenting. It is like the command “about-face which is a 180 degree turn. When any person comes to the point in their life that they are broken over their sin to the point of being ready to get right with God no matter what it will cost them they are in a state/spirit of repentance toward God.
We then take that heart that we have toward God and place it on the Lord Jesus Christ, for there is no other name under heaven by which men must be saved, and that becomes faith. At that point God's grace through Christ is applied to us and we are saved, born again, and will never turn back into the practice of sinning. It is a repentance/faith that is lived daily and never turned from as we are kept in that state by the Spirit. Acts 20:21, 1John 2:19 and 1John 3:9,10.
Repentance of sin is the result of our salvation (new birth), and will be part of the sanctification process in our new life with Christ Eph. 2:10. While we may sin from time to time after being saved no one continues in the practice of sinning or returns to it after salvation 1John 3:9,10
