Courage is an interesting concept. It’s not the same as being fearless - it’s more like the ability to recognize when that feeling of fear is there to protect you and when it’s there to stifle you, hold you back and prevent you from receiving God’s will for your life.
When you are in a situation the scares you - think about whether you’re walking in wisdom with God or being foolish. If you’re being foolish, then run! But if you’re walking with God - He says “Don’t be afraid,” even of the impossible - one of the examples we have was of walking on water - that’s crazy. God may ask you to do something crazy someday. Practice listening to Him and His voice. Let Him fill you with Godly courage and be and do all He created and purposes you to be and do!
