Notice how Paul and Peter say virtually the same things at times. Compare Peter’s exhortation to us with 2 Corinthians 6:6, where Paul expresses the fact that he indeed was behaving as Peter says we ought. The Bible is remarkably consistent, and the Apostles knew what the Spirit’s power could do in the life of a believer, and in uniting a fellowship around Jesus Christ. The Holy Spirit is the bond between believers (Ephesians 4:3-4), and He provides the power that we need to stay in fellowship together. It is not simply tolerance, but togetherness, growing in grace and trust of God and each other. We are to be fervent for the spiritual growth of our fellow brothers and sisters in Christ; after all, we are of the same body.
Fervently, think about that. When you love someone with a pure heart, and you love them fervently, you will stop at nothing to do what it takes to please them, to help them, to love them, no matter what. You are passionate about whatever it is you love fervently. You sacrifice for what you love fervently. You look to what you love fervently before your own needs. If what you love fervently has a problem you try and fix it.
This is just one more reason that believers must go to church; how can you love one another fervently if there are no “others”? Fervently doesn’t stay at home, fervently finds a way to fellowship. Fervently looks for the betterment of the whole fellowship. Fervently knows that everyone on the team is important. Fervently forges relationships that will stand the test of time. Fervently realizes that an on fire church starts with them. Is the whole of your fellowship fervent, and what are you doing to develop a fervent fellowship? If your church isn’t on fire, start a blaze by beginning to love others with a pure heart, fervently.
