But to whom little is forgiven, he loves little. However, the Christian's joy is of a different variety than the world's. The world cheers for the new car, vacation trips, and money they may win on game shows. A young man gives his girl a diamond ring or necklace, and seeing the sparkles, she excitedly jumps to him, showering him with kisses, because he gave her jewels. First of all, there is a 'love' for Christ.
Afflictions bring about patience.
Patience results in experience. And when we have been through His training, we have no need to be ashamed. When God deals with us in such a manner, and we have matured, we 'understand' His love for us. He doesn't merely 'save' us and let us wander about any ol' way we please. He nurtures us with His love, and we understand the Holy Spirit which is given to us.
