“The one who loves his brother abides in the light and there is no cause for stumbling in him” (1 John 2:10).
Loving other Christians gives assurance to your own faith.
Loving fellow Christians is instinctive for genuine believers. Paul told the Thessalonians, “Now as to the love of the brethren . . . you yourselves are taught by God to love one another” (1 Thess. 4:9). He further encouraged them to “excel still more” in love (v. 10) because there is always room for believers to love one another more completely. Nevertheless, if we are truly saved we will show love, since love is inherent in our new nature (see Rom. 5:5).
Jesus said this about love among believers: “By this all men will know that you are My disciples, if you have love for one another” (John 13:35). If we are truly Christians, we will “fervently love one another from the heart” (1 Peter 1:22). Love is a test of our divine life and signifies that we have crossed over from darkness to light (1 John 3:14-15).
The apostle John goes on to define love as being sacrificial and practical: “We know love by this, that He laid down His life for us; and we ought to lay down our lives for the brethren. But whoever has the world’s goods, and beholds his brother in need and closes his heart against him, how does the love of God abide in him? Little children, let us not love with word or with tongue, but in deed and truth” (vv. 16-18).
Therefore, you should ask yourself some basic questions: Do you care about other believers, or are you cold and indifferent? How do you respond to opportunities to give of yourself in various ministries? Do you look forward to having fellowship with other Christians—talking with them, discussing the things of God, studying the Word together, and praying with them? When you encounter a friend at church who has a need, are you willing to provide money, time, prayer, resources, service, or even a sympathetic ear?
If you can answer yes to those questions, you have great reason to be assured of your salvation. Like Peter, you can appeal to the love God sees in your heart (John 21:17). That love won’t be perfect, but it’s there and will manifest itself to others.
