We learn about the Son when we first become a Christian. We learn about the Holy Spirit when we receive the baptism with the Spirit. I believe it is now, at the present time, that we are being alerted to the fact that the Lord Jesus did not come only to bring us to Himself but to bring us to the Father. Jesus is the Way to the Father. It is time now for us to learn about the Father.
We gain the forgiveness of our sins through Christ. We gain victory over our sins through the Holy Spirit. We gain the crucifixion of our self-will as we learn to obey the Father sternly and completely. For this reason, we go through a period of suffering, like Job, so we may learn that we are the merest dust and only through Christ can we come to know the Father.
Compare the following two passages. Do you see how his tribulations changed Job and brought him to a fuller knowledge of the Father?
Though he slay me, yet will I hope in him; I will surely defend my ways to his face. (Job 13:15)
My ears had heard of you but now my eyes have seen you. Therefore I despise myself and repent in dust and ashes. (Job 42:5,6)
Job began as a righteous man. But the self-will in his was still very much alive. We can be a Christian and serving the Lord, and still be filled with self-will while we are doing our religious activities. But we cannot come before the Father in our self-will.
Before we can enter the rest of God, that state of being in which we are living by the Life of Jesus, we must through Christ gain victory over worldliness, the lusts and passions of the flesh and spirit, and self-will.
