“For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.” (Romans 12:3/KJV).
This is a very plain explanation of the meaning of the word ‘pride’: Thinking more highly of oneself than what is right to think. It is overestimating oneself.
Now here St. Paul is writing to members of the Christian church at Rome. By what standards ought Christian believers to evaluate themselves? Paul says faith is to be the standard.
Think of a football club. There may be some active members who have great skills that are not related to football. It may be interesting to know if somebody in the club should be a software specialist. But with regard to the goals of this association sportive abilities and football skills are the determining factor as for greatness. Whatever helps to gain victories at football matches would be first and foremost.
The apostle here says that greatness at church should be determined by the measure of faith somebody has received from God. The overall goal of a church fellowship is to strengthen each other in believing and trusting God. This also is the groundwork for any outreach of the church and witness to nonbelievers.
Church members have various skills and abilities to contribute to the fellowship of believers. In Romans 12 Paul mentions prophesying, serving, teaching, encouraging, giving, leadership and showing mercy. All these things should be done in a way as to help one another to honour God and trust God.
No Christian ought to say he does not need the other believers. We all are challenged to support and to strengthen each other in faith. For that we ought to exercise our natural and spiritual gifts. Our contributions to the body of believers are valuable in as much as we have learned to rely on God and to ‘abide in Christ’. (Cf. John 15:5).
