I’ve been spending time meditating on / researching John 13-17, and came across a sermon from Edwards on John 15:5. In the application section he gives six motives for Abiding in Christ, which I have put below. I encourage you to take some time and let your heart be refreshed as you think about Christ, the fountain of all spiritual life and joy.
There are six Motives that Christ in the context makes use of, to persuade his disciples to abide in him:
1. Because without him, they cannot bear fruit. We can do no good work, exert no holy actions, nor do anything that is acceptable to God, as in the 4th and 5th verses.
2. If we don’t abide in him, we shall be cut off, and shall be gathered up and burnt as dry and barren branches, as in the 6th verse. Therefore, if we are desirous of escaping the fire, let us abide in Christ.
3. Abiding in Christ is the only way to have our prayers heard and answered. And if we do so, whatsoever we ask shall be granted, [as] in the 7th verse.
4. By so doing, we shall glorify God, as in the 8th verse; which implies that by deserting him, we shall do what will be greatly to his dishonor. None so dishonor God as false professors, those that make a profession of Christ and in time of temptation fall away.
5. Christ has loved us, and thereby has laid under great obligations to abide in him. By departing from him, we shall be guilty of the basest ingratitude and abuse of his love, as in the 9th verse.
6. If we abide in Christ, we shall continue in his love. Christ engages to us, that if we are constant to him, he will be so to us, and that there is nothing but our inconstancy and our forsaking him that will separate us from his love, as v. 10.
