Because of their being “fleshly,” jealousy, strife and sectarianism existed among them.​—1 Cor. 3:1-4.

4. What questions might we ask about ourselves to determine whether we are “fleshly” or not?

⁴ Are any of us like that​—unstable, still inclined to follow men? Are some “fleshly” or worldly in their thinking, usually critical of their brothers and the work they are doing rather than working harmoniously with them under the headship of Christ? Are there some who have not as yet developed the love that motivates one to expend oneself for the upbuilding of the Christian congregation? Then they do indeed need to strive to attain Christian maturity.

Heb. 5:12–6:1.

6. How might some today be in need of similar admonition?

⁶ Are there any among us who have been associated with the Christian congregation for years and yet are not able to teach others the basic doctrines of the Bible? After years of association with God’s people, do some still have difficulty in letting their conscience distinguish right from wrong? Do they still want others to make decisions for them in matters of conscience? Any who find themselves still needing instruction in the basics of Christian teaching and living should certainly be working hard to acquire maturity. Christians should not be like builders who never get beyond the foundation of the building, the “foundation” in this case being elementary or primary doctrines about Christ. They should press on to complete the building or the superstructure that rests upon that foundation, namely, the more advanced teaching about God’s purpose as revealed through his Son.

7. Why is the immature Christian who fails to exert himself to grow up spiritually in a dangerous position?

⁷ The immature Christian who fails to exert himself to become firm in faith, progressing no farther than the elementary things of God’s Word, stands in grave danger.
