1. Christian unity requires spiritual maturity (v.1-4)
1 But I, brothers, could not address you as spiritual people, but as people of the flesh, as infants in Christ. 2 I fed you with milk, not solid food, for you were not ready for it. And even now you are not yet ready, 3 for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh and behaving only in a human way? 4 For when one says, “I follow Paul,” and another, “I follow Apollos,” are you not being merely human?
Ephesians 4:11-14: 11 And he gave the apostles, the prophets, the evangelists, the shepherds and teachers, 12 to equip the saints for the work of ministry, for building up the body of Christ, 13 until we all attain to the unity of the faith and of the knowledge of the Son of God, to mature manhood, to the measure of the stature of the fullness of Christ, 14 so that we may no longer be children, tossed to and fro by the waves and carried about by every wind of doctrine, by human cunning, by craftiness in deceitful schemes.
Hebrews 5:12-14: 12 For though by this time you ought to be teachers, you need someone to teach you again the basic principles of the oracles of God. You need milk, not solid food, 13 for everyone who lives on milk is unskilled in the word of righteousness, since he is a child. 14 But solid food is for the mature, for those who have their powers of discernment trained by constant practice to distinguish good from evil.
2. Christian unity requires humble servanthood (v.5-8)
5 What then is Apollos? What is Paul? Servants through whom you believed, as the Lord assigned to each. 6 I planted, Apollos watered, but God gave the growth. 7 So neither he who plants nor he who waters is anything, but only God who gives the growth. 8 He who plants and he who waters are one, and each will receive his wages according to his labor.
Mark 10:43-45: 43 But it shall not be so among you. But whoever would be great among you must be your servant, 44 and whoever would be first among you must be slave of all. 45 For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many.”
Philippians 2:3-5: 3 Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. 4 Let each of you look not only to his own interests, but also to the interests of others. 5 Have this mind among yourselves, which is yours in Christ Jesus,
Am I doing this for recognition?
Am I comparing myself to others?
Am I seeking to earn God’s love?
3. Christian unity requires proper identification (v.9)
9 For we are God's fellow workers. You are God's field, God's building.
Galatians 3:28: There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus.
1 Peter 2:5: you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ.
