Our only ally in any of this is truth. We can always count on the truth. Despite our feelings. We may not like what the truth says but truth trumps feelings at every turn. It is a foundational need for us as humans. Otherwise, we are all driven by selfish desires to do what we feel is right for us. Truth reminds us who we really are and that our hearts are "deceitful above all things, and desperately wicked: who can know it?" (Jeremiah 17:9 KJV)
One Person knows our hearts and its wicked state. That same Person, Jesus Christ, took our hearts and gave us new ones. His Truths reside there. He's also given us His Word to remind us of those Truths, lest we begin to listen to that old heart of our old Adam.
Our feelings are only worth anything when they are based in Truth. Truth only comes from God and His perfect Gospel. That's where our feet have been planted. If we trust our feelings only, we blow like a leaf in the wind. But His Truths transform us and calm us beyond what any feeling could ever do. Truth lasts from age to age. What is true is always true. Feelings come and go, blowing us in every direction. Let us hold fast to the Truth of Christ's life in us. If THAT gives you a good feeling, it should! It does me!
