Hebrews 12 vs 12 is a reminder to us as believers to lift up our hands that hang down in despair and our weak knees. The adversary likes christains to be weary so they can be exploited. God wants us to rise in worship. Lift up your voice and worship in your state. Exalt the one who remains strong in our difficulties, He is already in the future. By doing this, you become strengthened to withstand the storm and hear His voice.
