Philippians 4:6-8
Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus.
Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
We have a choice on what thoughts we dwell on. What we think on will run our lives.
We can choose to dwell on the negative (no one cares, nothing ever turns out right, I’d be happier if…). Or we can choose to think positively (God loves me, count your blessings, meditate on Scripture, pray, spend time encouraging someone else).
When we guard our thoughts against the wicked lies of the devil and choose to trust the Lord, we free ourselves from fear and worry. This in turn gives us a peace that passes all understanding.
