We have to rest in the reality of who God is and trust our life to him. When you surrender your heart to him, a peace that surpasses all understanding will flood you heart.
When Abraham surrendered to the Lord, he became a father to many nations. When Jonah surrendered to the Lord, God used him to bring an entire city to repent. When Saint Paul surrendered to the Lord, God used him to speak to nations and to write most of the new testament.
Imagine what God could do if you surrenderer your heart to him?
“Commit to the Lord, and thy works and thy thoughts shall be established.” (Proverbs 16:3)
