Maturity is not complimented by complexity.
Neither is depth the fruit of study or asceticism. The riches that are to be found in Christ are profoundly simple and are revealed by revelation.
Those who pray according to His Word will see and know Him. If He can only be known by faith, the playing field has been levelled. Young and old can know Him. The educated and the mentally handicapped can know Him.
Soldier of The Cross, the issue is faith. Can He be believed or not?
It is simple. Just not always easy.
Agreeing with God takes place in prayer.
