The disciples that Jesus called were uneducated, and were far from being perfect in character when Jesus united them with Himself; but they were willing to learn from the greatest Teacher the world ever knew. They were truly converted men, and became the new bottles into which Jesus could pour the new wine of His kingdom. But though they were converted to Christ, yet, because of their limited earthly comprehension—the result of the teaching they had had from the Jews—they were unable fully to understand the spiritual nature of the truth He could impart. The burden of His instruction was the necessity of His followers having pure and holy hearts, for holiness alone would fit them to become subjects of His heavenly kingdom. (LHU 259.3) MC VC
