The seventh verse of the sixth chapter of the Epistle to the Galatians: â€œBe not deceived; God is not mocked. For whatsoever a man sows that shall he also reap.â€ This admonition is given by the Apostle in immediate connection with the subject of contributions to the work of the Lord. He has just said to the brethren, â€œLet him that is taught in the Word communicate unto him that teaches in all good things.â€ And he says just below, in the same connection, â€œAs we have opportunity let us work that which is good toward all men, and especially toward them that are of the household of the faith.â€
The Work of the Spirit: Guide (16:12-13)
There was another work of the Holy Spirit for the apostles which would be for the benefit of the apostles and why Jesus would go to the Father. Jesus still has many things to teach his apostles. But he is not personally going to do this because they cannot handle his teachings yet. Rather, Jesus is going to send the Spirit of truth. The Spirit will be the one who will guide these apostles into all the truth. This is a very important promise. Who is all truth given to? All truth is not going to be directly given to every Christian. All truth will be directly given by the Spirit to the apostles. This is exactly what Paul taught the Christians in Ephesus.
When you read this, you can perceive my insight into the mystery of Christ, which was not made known to the sons of men in other generations as it has now been revealed to his holy apostles and prophets by the Spirit. (Ephesians 3:4–5 ESV)
Notice the revelation was made by the Spirit, not to everyone, but to his holy apostles and prophets. The apostles and prophets wrote those things down so that we can have the same understanding and insight that they had. Just as Jesus spoke the very words of the Father with the authority of the Father so also the Spirit of truth will speak the very words of the Father with the authority of the Father. The Holy Spirit would not speak directly to all Christians nor offer every Christian personal guidance. Jesus promised that the Holy Spirit would be delivered to his apostles. The apostles would receive all of the truth and they would be personally guided by the Holy Spirit. The glorious hope for us is that when we read the scriptures, we are able to understand all of the same information as the apostles. Paul told the Ephesian Christians that they would have the same insights, not by direct Holy Spirit intervention or communication, but by reading what the apostles and prophets wrote down because they wrote down the full revelation of truth from the Holy Spirit.
