God loves us, and He has provided us with the Living Water of His love. As we drink of this Living Water, we will be filled with His love, and it will flow out to others. This also includes walking the way of the cross.
Satan provides counterfeits - cisterns of the world. They will never satisfy. Some of these cisterns are youthful lust, accomplishment, and human approval. They will run out, just like natural cisterns, all that's left is emptiness that we can't fill.
The only way to be filled is to drink from God's Living Water.
