The reality is, that no matter how sweetly, calmly, or politely you disagree with somebody,
when you contradict their assertions and challenge their paradigm,
many people will get angry.
That's just how humans work.
We should still try to be polite and respectful.
But being more polite still won't fix the problem.
We should be polite just because it's the right thing to do...
but it won't really stop everyone from getting upset.
I understand that but this is why we are told to operate in the fruit of Spirit, and one of those is patience in dealing with those who want to be contentious.
Those who come out and just start in with heated or demeaning comments still need to learn by the Spirit to bridle their tongues, and if we are not around to point it out to them how are they to know how they are acting is not the correct way to carry oneself in the faith.
We are called by the Holy Spirit to be overseers of the rest of the flock to point them in the right direction !!!
(Acts 20:28)
Show me where in the NT do any of the books agree with Jesus' teaching on forgive others or the Lord won't forgive you. Show me one verse. I will let you know ahead of time that the verse you will find is one that says to forgive others because the Lord has forgiven you for Christ's sake. Notice that we have His forgiveness already and we aren't doing anything in order to obtain it.
Again that is your misunderstand of Apostle Paul as I just brought up and showed you before.
Of course Apostle Paul would use the past tense when it comes to forgiveness because when we first came to the faith and repented of our sins and got baptized into Christ we were given remission of our sins at that point of those we had already committed.
From here all the Apostles especially Paul tell us how to keep from stumbling and returning to a sinful lifestyle, therefore there should be no need to go back to repentance. But as Apostle John shows as well as Paul that
"if" not "when" we sin again we will be forgiven when we confess it to the Lord and return to continue walking in the Light/Spirit.
The fact of not forgiving others comes from a unforgiving heart, and those who have no forgiveness in them do not have eternal life abiding in them to begin with !!!
This is the main reason Paul uses a past tense understanding because by that point in our walk and being born again we should automatically have a forgiving nature, as a unforgiving nature is not of God therefore that person who walks as such can not be of God either.
For forgiveness is love, and love is God !!!
