Here is a wise word from J.C. Ryle to “teachers of souls” concerning young believers and their discipleship. Reflecting on Matthew 9:14-26 in Expository Thoughts on the Gospels (Vol. 1), Ryle says:
We must be careful not to attach an excessive importance to the lesser things of religion. We must not be in a hurry to require a minute conformity to one rigid rule in things indifferent, until the first principles of repentance and faith have been thoroughly learned. To guide us in this matter, we have great need to pray for grace, and Christian common sense. Tact in dealing with young disciples is a rare gift, but a very useful one. To know what to insist upon as absolutely necessary from the first–and what to reserve, as a lesson to be learned when the learner has come to more perfect knowledge–is one of the highest attainments of a teacher of souls.
The fundamental elements of Christianity are the building blocks for the life of a Christian. Once the foundation has been built, the rest of the house can begin to be framed.
