We do not have to live at the mercy of our fears and emotions. Anxieties and emotions will ebb and flow, but it is possible to live in such a way that we begin to believe the truth that God loves us and that what He says is more true than our thoughts and emotions.
Some practical ways to do this:
Fill our minds and hearts with the truth of God’s Word (John 17:17) ~
Let His Word, the Bible, be the definition of truth rather than your thoughts/emotions. Find verses that contain TRUTH about who God is and how He sees you/feels about you as one who believes in Him. Memorize them! Sing them! Pray them!
Take every thought captive (2 Corinthians 10:5) ~
When our minds are filled with anxious thoughts or accusations against God or others, we can choose to replace those thoughts with truth and renounce the things that are lies or have no basis in reality.
Set your mind on things above (Colossians 3:1) ~
I like to specifically think about (meditate on) what God is like. Choose a passage such as Revelation 4 or Psalm 145 and speak back to Him (prayer) who He is and what He is like. Doing this especially when I want to dwell on my own fears, failures, or worries is so helpful to get my focus back on Him!
Fight the fight of faith (1 Timothy 6:12) ~
Hebrews 11:6 tells us that we must come to God believing that He IS and He is a rewarder of those who seek Him. We have to actively CHOOSE to believe, often before we feel it, that God is Who He says He is, and that He truly feels towards us the way the Word describes He does.
Over time, as we choose daily to believe, we will see transformation! Our thoughts and emotions will begin to respond to the truth of God’s Word. Don’t give up!
