It's the same when we have problems in our lives!!! Whether it's a health issue, trouble in a relationship, dealing with the loss of a job, etc., ignoring the doubts, the fear, the anger, doesn't make these feelings or problems go away! I agree that sometimes we just gotta suck it up and put on our poker face, and, yes, sometimes that helps temporarily. But in the quiet, when we're all alone, sometimes those thoughts, fears, or doubts find themselves creeping back in. Instead of pretending they are not there - GO TO GOD with them. Don't let them just sit there with the enemy and incubate more negativity and doubt in your mind!!! BRING them to the light, bring them to GOD!!!! Let's His Truth pierce through the lies!! When our feelings fail us, we can run to the truth of God. Don't let the enemy have a hay day. Go to God. Bring your fears, bring your doubts, bring your anger - to HIM.
Philippians 4:6 "Don't worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. Then you will experience God's peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus."
