New Defender's Study Bible Notes
1:18 after three years. Even before such a learned man as Paul was truly fit to preach and teach God’s Word, he must spend three years alone with Christ, as it were, just as the eleven apostles had spent three years being taught by Him. It is presumptuous for a new convert to think he is ready for such a ministry before he also has spent at least the equivalence of three full years in intensive study of the Scriptures. Note the warnings in I Timothy 3:6 and James 3:1.
