The sin of ancient Israel was in disregarding the expressed will of God and following their own way according to the leadings of unsanctified hearts. Modern Israel are fast following in their footsteps, and the displeasure of the Lord is as surely resting upon them.
It is never difficult to do what we love to do, but to take a course directly against our inclinations is lifting a cross. Christ prayed that His disciples might be one as He was one with the Father. This unity is the credentials of Christ to the world that God sent Him. When self-will is renounced in reference to matters there will be a union of believers with Christ. This all should pray for and work for determinedly, thus answering as far as possible the prayer of Christ for unity in His church.
