28:9 Paul had necessarily adapted his manner to teaching to the condition of the church. "I, brethren could not speak unto you as unto spiritual," he afterward explained to them, "but as unto carnal, even as unto babes in Christ. I have fed you with milk, and not with meat: for hitherto ye were not able to bear it, neither yet now are ye able." 1 Corinthians 3:1, 2. Many of the Corinthian believers had been slow to learn the lessons that he was endeavoring to teach them. Their advancement in spiritual knowledge had not been proportionate to their privileges and opportunities. When they should have been far advanced in Christian experience, and able to comprehend and to practice the deeper truths of the word, they were standing where the disciples stood when Christ said to them, "I have yet many things to say unto you, but ye cannot bear them now." John 16:12. Jealousy, evil surmising, and accusation had closed the hearts of many of the Corinthian believers against the full working of the Holy Spirit, which "searcheth all things, yea, the deep things of God." 1 Corinthians 2:10. However wise they might be in worldly knowledge, they were but babes in the knowledge of Christ.
