"Trust in Him [the Lord] at all times, you people; pour out your heart before Him; God is a refuge for us."
What are your problems, concerns, and/or heart-struggles today? Have you sought to trust God for their resolution? You might be discouraged, because you still feel "jittery," nervous, and anxious about these things--even after bringing them to the Lord in prayer.
That is all right. The main thing is that you are, by grace, entrusting yourself and your issues to Christ. If you are owned by the Redeemer--if His blood has atoned for you--then you are a whole lot better off than you think you are. Don't kick yourself when you are down. God doesn't do this to you.
[Puritan quote of the day: "That Great Physician [Christ], as He had a quick eye and a healing tongue, so had He a gentle hand, and a tender heart." --Richard Sibbes, in "The Bruised Reed"]
