In whose words does Paul speak the things of the Spirit of God?
Paul speaks the things of the Spirit of God not in words taught by man's wisdom but in words taught by the Holy Spirit, comparing spiritual things with spiritual. The Spirit reveals these things freely through the Word, not by fleshly energy.
Les explains that the Creator, Sovereign God is the One who reveals these things to us, and we must look at them in that light. This knowledge is not attained in the energy of the flesh; it comes as the Holy Spirit works through the Word and reveals it freely. In verse 13, Paul says, 'Which things also we speak?'—the things of the Spirit of God—not in words which man's wisdom teaches, but which the Holy Spirit teaches. Les notes that Paul teaches by comparing spiritual with spiritual. He then applies this: your eternal destiny cannot be judged by outward appearance, for only God can discern, but you can know by lining yourself up with the Word of God. He illustrates with a young lady who came into his home Bible class and accused him of teaching a heresy.
Which things also we speak, not in the words which man’s wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
