The Cross of Christ - The Throne of God by F G Huegel and published by Classics.
There can be no true Christian experience except the Cross be the fountain head. Christians do not enter into the glories of the Christian life in union with Christ, until they learn to glory in the cross, like Paul who so identified his very life, and purposes, and all, with Golgotha’s Ignominious Tree that he dared say: “I am crucified with Christ”. The deeper the Christian sinks his life into Christ’s death, the more he has of His life. These chapters have no other purpose than to impart to all Christians, especially preachers & missionaries, the secret of triumphant living in Christ - the secret of fruitfulness.
