1 Corinthians 2:10, Revealed by His Spirit
The Holy Spirit indwelling the born-again believer illuminates the mind so that he is able to understand God’s Word.
The Holy Spirit’s guidance was Jesus’ promise to His disciples before He went to the cross prior to His death, resurrection and ascension to heaven. Though He will not be bodily with them, His Spirit will help them – John 16:13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
