One of my favorite verses in the entire bible is Philippians 4:6-8:
"Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all comprehension, shall guard your hearts and your minds in Christ Jesus. Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, let your mind dwell on these things."
Another is Matthew 6: 31-34:
"Do not be anxious then, saying, 'What shall we eat?' or 'What shall we drink?' or 'With what shall we clothe ourselves?' "For all these things the Gentiles eagerly seek; for your heavenly Father knows that you need all these things. "But seek first His kingdom and His righteousness; and all these things shall be added to you. "Therefore do not be anxious for tomorrow; for tomorrow will care for itself. Each day has enough trouble of its own.
I try to take strength from these verses. I truly do, but more often than not, I fall back into worry, anxiety, depression. I wish there were a magic pill that I could take that would make me be 100% faithful every day and that would wash away my doubt.
If wishes were horses...
I've found myself changing my habits, and it's making a difference.
