A union with Christ by living faith is enduring; every other union must perish. Christ first chose us, paying an infinite price for our redemption; and the true believer chooses Christ as first and last and best in everything. But this union costs us something. It is a union of utter dependence, to be entered into by a proud being. All who form this union must feel their need of the atoning blood of Christ. They must have change of heart. They must submit their own will to the will of God. There will be a struggle with outward and internal obstacles. There must be a painful work of detachment, as well as a work of attachment. Pride, selfishness, vanity, worldliness–sin in all its forms —must be overcome, if we would enter into a union with Christ. The reason why many find the Christian life so deplorably hard, why they are so fickle, so variable, is, they try to attach themselves to Christ without first detaching themselves from these cherished idols.
After the union with Christ has been formed, it can be preserved only by earnest prayer and untiring effort. We must resist, we must deny, we must conquer self. Through the grace of Christ, by courage, by faith, by watchfulness, we may gain the victory.
