Every person who belongs to the kingdom of God was at some point born again. When you are born again, you become babe in the kingdom. From that time onwards you have to work on your growth. Conditions for growth must be provided so that we grow. The bible tells us that God gives this growth or increase. But remember we have those who are assigned to water. Remember Paul said he planted, Apollos watered but God gave increase. We cannot afford to have people in church yet not growing. A good illustration would be 2 children with the same parents living together given all are eating, the one who was born first appears to be bigger at most because he has consumed more food. If the older does not eat, we might face a challenge of identifying the oldest. We feed on the word of God which is able to build us up.
