He took with Him the problems of the time and went there to pray, to seek His heavenly Father's will.

Theology needs a system.
The different branches of theology need coordination, need to be brought into line with each other, need to be unified as a whole. We need to make sure there are no contradictions between them. An individual person's theological thinking needs to become a harmonized whole. One's theological viewpoints need to hang together. We don't want to talk about one thing one moment and then suddenly find ourselves maintaining the opposite or the negative of that viewpoint the next moment.
