To still a trembling heart?
Our hearts tend to tremble when fear arises. Fears take so many forms – some from trauma, some from physical cues, some from imposed affliction, some from self inflicted explosions.
Be still. Breathe. Be mindful.
All good advice. But you need to add the shield.
Know that God is God. Not just any god, or any invented perception of god. Not just an idea but a God who is there, is not silent and enters into our world.
Find the God that is fearful. In such a way that there is nothing that God cannot do. Nothing that God does not know. Nothing that God cannot fix.
Then fix yourself on that God. Literally, be fixed by that God.
And your heart will beat in rhythm.
