[2 Corinthians 1:21-22] says that God has anointed us, has sealed us, and has given us the pledge, the foretaste, of the Spirit. If we are going to minister something of Christ to others, we have to experience Christ by the working of the cross, and the working of the cross is for the anointing, the sealing, and the pledge of the Spirit.

Second Corinthians speaks concerning the ministry, which is constituted with, and produced and formed by, the experiences of the riches of Christ through sufferings, consuming pressures, and the killing work of the cross. The ministry is not merely a matter of gift. A person may be able to speak fluently and eloquently and give many good illustrations and proverbs, but this is just a gift. What the church, the Body, needs today is the ministry.

The central thought of the Scriptures is that God intends to work Himself in Christ through the Spirit into us, that God and we, we and God, might be really one in life, in nature, and in the Spirit. To show this God uses several figures or symbols in the Bible.

The Corinthians talked about spiritual things, but they did so in a fleshy and sourish way. The apostle Paul told them in the first book that they were fleshy and not spiritual (3:1), and in chapter 2 of the first book, he spoke of sourish men (v. 14). A spiritual man (v. 15) is one who does not behave according to the flesh or act according to the sourish life but lives according to the spirit, that is, his spirit (Rom. 1:9) mingled with the Spirit of God (8:16; 1 Cor. 6:17). Such a one is dominated, governed, directed, moved, and led by such a mingled spirit. Although the Corinthians spoke much about spiritual things, the apostle Paul designated them as fleshy and sourish. They were talking about spiritual things in the soul and in the flesh. Some may talk about the heavenly things in Ephesians, but they do so as Corinthians—in the soul or in the flesh.

The experiences mentioned in this book are experiences in the Holy of Holes. This book gives a portrait of a person who is in the Holy of Holes. Paul and his co-workers were such persons. They had entered into the good land and were living in the spirit, experiencing Christ all the time. They were deep, even the deepest, in the experience of Christ.
