God is calling each disciple of the Christ to be increasingly transformed into his Son's likeness (2 Cor. 3:18). It is one thing to be in Christ, it is another to live out the implications of Christ living in us. The Lord Jesus Christ indwells every believer in the person of the Holy Spirit, and as we grow in the grace and the knowledge of the Lord Jesus, every disciple reflects more and more of Christ and less and less of self-by the power of the Holy Spirit. The following chapters first appeared as individual articles in Life in the Spirit journal over a period of some twenty years. Each chapter addresses some aspect of the Christ-life, and is based on what God in Christ has done for us through the salvation events (the atoning death and resurrection of Jesus Christ). The emphasis in this book is primarily about what the Lord Jesus Christ is presently doing in us, through the ongoing ministry of the Holy Spirit. I pray this volume will be used by the Holy Spirit to encourage each reader to live the Christ-life-to the glory of God in the power of the Holy Spirit.
