Loving God is not just in what we think to ourselves. We could be the most loving people, in our minds, but if all we are practicing is hatred then we are no better than liars. A person who hates his or her brother or sister in The Lord is a liar because though they claim to L/love God, they actually do not. Loving God is about how you treat everyone around you; not just in the declarations you make about how loving you think you are.

And we pray:
Dear God, I pray that I never be someone who is all talk and no action. Father, if there is anyone I am harboring resentment or hatred against, may you help me release such emotions, Lord. They are not of you. I desire to love everyone around me, Lord, as you will me to. In Jesus’ name, I pray. Amen.
