We must come to understand the depth and essence of His precious love, and we have to. He willingly laid down His life for us because of His great love. That's how wide His love for us. And, we ought to lay down our lives for the believers.
This is how we’ve come to understand and experience love: Christ sacrificed his life for us. This is why we ought to live sacrificially for our fellow believers, and not just be out for ourselves. Extend love. Spread the love just like God spread His love to everyone.
