Pastor Brian Morgan said this in a comment on my post yesterday:

Our progress of sanctification is not illustrated by our position on this matter. But how we treat others who might disagree with us may indeed be illustrative!

How many decisions in life are like that!  There are many things where the Scriptures give clear and direct instructions, and our response does reflect our Christian growth.  But in many decisions, mature and obedient Christians may choose differently.

But even in things the Bible commands, how we treat those who disagree says more about us, and our progress in sanctification, than about them or the question at hand.  After all, the following instruction guides our dealings with those in sin.  How much more would it apply to those who disagree on matters that are not sin!

II Timothy 2:24-26

24 And the servant of the Lord must not strive; but be gentle unto all men, apt to teach, patient,
25 In meekness instructing those that oppose themselves; if God peradventure will give them repentance to the acknowledging of the truth;
26 And that they may recover themselves out of the snare of the devil, who are taken captive by him at his will.
