It is possible to be spiritually immature. Christianity is not a feeling; it is a deeply rooted understanding. The Word of God transcends time, so when the writer of Hebrews says, “by this time you ought to be teachers” (Hebrews 5:12), he is not just addressing the church of that day, but all believers. So, for us to be teachers of righteousness, we must be mature Christians, being able to articulate, with understanding, the things of God.
Jesus appointed the twelve disciples so that He could send them out to preach, but before He could send them, they first needed to be with Him (Mark 3:14). We are called to be with Jesus. We can’t know and understand Him without being close to Him. We learn to know His voice and His will when we abide in Him (John 15:5). Whenever we are disconnected from God, we make decisions based on our natural reality/circumstances or feelings, and if left unchecked, will result in chaos.
Even though there are certain things that we don’t understand right now, that are hidden from us, as we spend time with Jesus and we see how He does things, over time it is revealed to us. He doesn’t leave us when we don’t understand or when we make mistakes. As long as we stay close to Him, sensitive to His voice and willing to learn, we’ll gain understanding and be able to step into the position of teachers.
