The two years you have offered for the training will definitely not be wasted because in the training you are studying the truth, pursuing life, exercising to pray much, learning to coordinate in spirit with the brothers and sisters, and learning to serve in the church. 

If all the young saints could set aside a segment of time for this kind of learning after they graduate from college, this would be a great benefit to them both in the increase of their spiritual deposit and the building up of their character.
