My thoughts...
Sometimes I find it takes a whole lot of wisdom to discern where to draw the line.
2nd Timothy teaches us:
2Ti 4:2 Preach the word! Be ready in season and out of season. Convince, rebuke, exhort, with all longsuffering and teaching.
and Titus teaches us:
Tit 3:9 But avoid foolish disputes, genealogies, contentions, and strivings about the law; for they are unprofitable and useless.
Tit 3:10 Reject a divisive man after the first and second admonition,
Tit 3:11 knowing that such a person is warped and sinning, being self-condemned.
There are a couple things I try to take into consideration....firstly...there is...IMHO...a difference between someone who is simply sharing their understanding...and those who set out to teach others.
Personally...I have a whole lot more patience with those who share their thoughts and may lack understanding...than I do those who set out to teach others such things that is plainly in conflict with Scripture.
Teachers of the Law...I find it's usually best not to get into lengthy and divisive discussions with them...it's usually best to present Scripture, share our thoughts and allow the Holy Spirit to move as He sees fit.
Sometimes I think, particularly on these boards, we have an inclination to keep plugging away to convince others and rebuke false doctrine...
Which is all well...until I realize...God doesn't need me to further His Kingdom business...He can use me...but He certainly doesn't need me...
...and if I step back...and God really wants to make a point...He'll raise up someone else...and perhaps He prefers to use someone else....because...the really cool thing I see from time to time is this...ministering to others is a two-way street...and many times...well prolly ALL the time...in ministering to others...we get ministered to in return.
We always have to be prayerful that when we step out to share the Gospel and the understanding we find in Scripture...that we are operating in the Spirit and not in the flesh...
...and just like Titus teaches us...regarding strife and division about the Law...we need that discernment to know when to walk away from a divisive
argument and trust God knows all about it and He has it all under control.
Titus prefaces the intruction regarding divisiveness in the Law with:
Tit 3:8 This is a faithful saying, and these things I want you to affirm constantly, that those who have believed in God should be careful to maintain good works. These things are good and profitable to men.
When our discussions are no longer profitable or beneficial ( the words of our lips are also a good work IMHO)...then perhaps the discussion should end.
~tiptoes back out the way I came in...
