“Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God.” (I John 4:7 NIV).
Everyone who loves others is a true Christian. The love of God is not like the counterfeit love found in this world. The counterfeit love found in this world is actually a selfish love that gives in order to get. We must model our love after Jesus, who died for everyone in the world (I John 2:2), even when He knew ahead of time that many of them would reject Him.
True love can only come through repenting and Believing in Jesus Christ. It cannot come through human effort, but God will give it to use freely if we ask Him for it and surrender our lives to Him.
