The Lord Jesus Christ on the cross is our ultimate example of love. True believers look at that model, and it motivates them to follow His lead in loving our brothers and sisters in Christ. Without that love, they become like Cain, who is of the evil one and killed his brother Abel. Those kinds of people are said to abide in death. It is incompatible for Christians to love like the world because their lives have been changed from death to life. Their new nature no longer has mastery over their lives. One way to tell is that they have an otherworldly love for their brothers and sisters in the Lord. They serve them the same way Christ served His disciples, demonstrating that true love is done with action. An exposition of 1 John 3:11-18.
