1 John 4:12-16...
What characterizes the deepest essence of God is love—that is, willing the good. His very creation of the world is an expression of willing the good. It’s expected, therefore, that his world would be found by him to be “very good” (Genesis 1:31). His love and goodwill toward humans is not an add-on to a nature that is fundamentally careless or even hostile. Love expresses what God always is in every respect.
God intrudes in our world gently and in many ways, but especially in the person of Jesus Christ. It is he who stands for love, as no one else has ever done. His crucifixion is the all-time high-water mark of love on earth. “While we were still helpless, at the right time Christ died for the ungodly” (Romans 5:6). No other source, whether inside or outside of religions, even comes close to the love that God shows in Christ. This is the first “move” of love in the process of redemption: “He first loved us” (1 John 4:19).
When we receive the revelation of God’s love in Christ, that amazing love makes it possible for us to love in turn. His love awakens our love for him. Therefore, the first Great Commandment—to love God with all our being—can be fulfilled because of the beauty of God given in Christ.
At the same time, we begin to love others who love God. And when “we love one another, God abides in us, and His love is perfected in us” (1 John 4:12). The first Great Commandment makes it possible to fulfill the second Great Commandment: love of neighbor as oneself. The kingdom fellowship of Christ’s apprentices is a community of love (see John 13:34–35). This is how love is made perfect or complete. And “perfect love casts out fear” (1 John 4:18).
