One of mine has always been Psalm 3:3 (ESV)
This simple verse with its rock solid declaration of God's protection has always ministered to my soul in ways that have rescued my heart from despair and hopelessness and the gloom of whatever situation had driven me back to its timeless relevance.
God is my shield. He is aware of my need. He knows my situation and he is and will be a shield about me. And with him as my protector, I have nothing to fear. He holds the shield, and I am safely under the protection of a powerful warrior who defends me and looks out for his own. He can be trusted. In fact, he is "the glory and the lifter of my head." The second line of the couplet is a statement that God will vindicate those who walk with him no matter what is going on around them. There are times when I desperately need to know this and I suspect that the same is true for many of you who are reading this as well.
Your husband is accusing you of not supporting him.
Your children scorn your faith.
Your wife is disinterested in following Christ.
Your children are wandering from the truth.
Your family is disfunctional in ways you can't even begin to describe.
Your debts are greater than your yearly income.
Your boss doesn't seem to understand your job and is uninterested in listening to your explanations.
You have been falsely accused on trumped up and inflated-out-of-context-stories.
You classes are boring and your life direction is unclear.
These confusions and frustrations are all soothed by the message of Psalm 3:3. "Trust in God don't give up; keep your hope in Him; He will be your shield; He will lift your head; He will vindicate your way--if your way is truly His. Don't give in. Keep fighting for the truth."
These truths have "worked" for me for years.
But every now and then, you come face to face with a new situation, a new set of circumstances that don't really challenge the truth of such conclusions and beliefs as much as they challenge your willingness to trust them at a new level.
Or maybe God recalls to your mind another Scripture that is equally true but deepens your understanding of what it means to become like Christ, to trust in God when everything in your spirit seems to cry out through every pour of your skin, RUN!
[Tomorrow, I'll try to talk about what you do then.]
