If someone is actively working against you, it is difficult to accomplish anything that you want to. Now imagine that person starts working with you. You can accomplish so much, much more than if you were simply working alone. Our relationship with God is the same: we were His enemies before He mercifully sent His son to guide us. Now we have the option of being on the same side. The choice is simple.
And we pray:
Loving God, my strength and light in the world, I rejoice in Your love. With this prayer I hope to thank you for sending Jesus to live and die for us, for we would truly be lost without him. Give me the wisdom to follow You more closely, Love more dearly, and trust everything else to You. In your name I pray, Amen.
