There are commands from God to love. These commands are to be applied to wives, brothers, neighbors, aliens and enemies. This love is that love that God had for us when Jesus Christ died for us. It is designed to be effective. It worked for our salvation.
Love requires an object and love requires expression.
The world was love's object and giving was love's expression. It was complete and more than adequate for all of the sins and sinners in this world. In obeying these commands to love we are to love as God loved. That is unconditional and without reserve or reluctance. We should have and give more love to the person needing love so that his need for love is satisfied.
