God's love was demonstrated. In this demonstration, God taught us that love is not a feeling. It is an action. It has consequences.
If God loved us while we were still his enemies, what does that mean for us? It means God's love ought to transform us so we can love others the way he loved us.
God's love reminds us both who we are and whose we are.
When we remember the gospel, we are reminded that we are saved. In a great act of love, we were rescued and redeemed. We are victorious in Christ! It also reminds us that we belong to God. We are who we are and where we are because of God!
God's love calls us to serve others, not segregate them out of our lives.
Just as God served us when he could have allowed us descend even deeper in our own depravity, his love compels us to serve others. Often, we remove people from our lives that we don't want to deal with. God's love compels us to serve instead of segregate.
God's love calls us to help others, not hate them.
In our deepest moment of need, God helped us. God would have been just to dismiss on the basis of our sin. But he chose to help us, in Christ. Our challenge is to grow in godliness to where the love of God pushes us past our hatred of others to help them in finding the way to God.
Let the love of God fill you, control you, and guide you in his service.
