1 Corinthians 3:21-23 (NET)
So then, no more boasting about mere mortals! For everything belongs to you, whether Paul or Apollos or Cephas or the world or life or death or the present or the future. Everything belongs to you, and you belong to Christ, and Christ belongs to God.
When Apostle Paul wrote 1 Corinthians, the church in Corinth was divided. Some said Paul was their apostle, others said Apollos was their apostle, and some others said Cephas was their apostle. Because of this, there were divisions among them. Paul made it clear to them that these divisions were simply a sign of spiritual immaturity (see 1 Cor 3:3-4).
Today, there are many denominations in the global Church, and each having their teachers, apostles, etc. There is nothing wrong with denominations as long as the people realize that the church is one, and all things, including ministers of God outside their denomination, belong to them.
God never planned for his saints to receive from only one kind of ministry gift (see Eph 4:11-12), but that is exactly what happens to believers who continually limit themselves to one minister of God. Such a believer would not grow to his full capacity because he lacks spiritual balanced diet.
If a minister is going to be truthful and humble, at certain points he would have to admit that there are certain kinds of graces that he has not been given. Even the great apostle Paul knew that he didn’t have grace for apostleship to the Jews–that was Peter’s department (see Gal 2:8, Rom 11:13). Churches established by Paul received from the ministry of Peter, John, James and even Jude. That was the culture of the church.
Go into today remembering that all true ministers of God belong to you and you should be blessed by their unique grace if you belong to Christ. Do not limit yourself by being closed-hearted.
