At some point we've each faced that feeling. So what do you do with it? How do you react? What do you say? What do you think? What is your response? I do know this, it's not healthy or even helpful to live there in that anxious fearful emotion. We must have another, more powerful, thought that leads to a better healthier emotion.
I believe if we can replace that fearful thought with a faith-filled thought we then have a hopeful faith-filled emotion that follows. Make sense?
For example, I was talking to a good friend of mine about some of my cares and worries and he said, "Timmy, don't worry bro God's got you!" And with that one thought I was able to replace my fear with hope. And I begin to dwell on that, and think, "yes God does have me, He always has, and always will."
One of my favorite verses:
Philippians 4:6-7 Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. - NIV
So to you I say, "(insert your name here) that thing you are going through, don't worry about it! God's got you! You are going to make it."
