The youngest believer, and the least gifted, has in his soul an experience of Christ's pardoning love, which is profitable for the most advanced saint to hear. Evidently the apostles did not disdain the company or conversation of young converts. God has given to us this duty of mutual submission to check ugly faults in our unsanctified natures. Nothing blows up our proud hearts so much as being elevated to some place of importance in the church. Not without cause has Satan been, through the centuries, an advocate of unscriptural offices in the church.
High office produces, as a rule, high-mindedness.
Even the biblical offices of elder and deacon are enough to elevate some professing Christians so high that they look down on lesser brethren as hardly worth listening to. It is to curb and cure this superior spirit that God bids all his people, the great as well as the small, to 'submit to one another'. There is another good reason why Scripture bids us be subject one to another. There are churches and fellowships which become so exclusive that they will have no fellowship with any but those of their own group. This is a regrettable and an unscriptural attitude to adopt.
