Maturity in the body of Christ is necessary to continue to understand the ways of God. We don’t instantly understand all things at the moment of salvation. As time passes, we develop wisdom through studying the word of God and through prayer. If we stay diligent, we will learn how to differentiate between truth and error, good and evil and divine will and personal feelings.
Lack of growth and spiritual maturity is dangerous for the believers. One can be easily deceived, tossed around and easily distracted by new teachings that come our way. (Ephesians 4:13-14) Spiritual maturity would enable us to become more familiar with the deeper spiritual truths of Christ.
Growing up is not optional for a believer’s life. Spiritual immaturity should not be normal in our lives after salvation. God has greater hopes and plans for our relationship with Him.
Hebrews 5:11-14
