That we henceforth be no more children tossed to and fro and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive
Ephesians 4:14
The importance of growing up spiritually cannot be overemphasized.
One of the proofs of maturity is the ability to discern. As you grow in the knowledge of the word, you will be able to tell the difference not only between good and bad but also between good and nearly good.
For the believer, his refusal to grow up in the things of the Spirit makes him gullible to deception
It is important to know that God has reconciled us to Himself and has given us the ministry of reconciliation (2 Corinthians 5:18-19).
Commitment to growing up in the word of God will make the believer active and effective in the work of the ministry to which he has been called.
Prioritising your spiritual growth enables you to help others to disciple them for Christ.
Spiritual growth helps the believer to accurately discern spiritual things.
He knows accurately what God wants.
