It is well with my soul ! I love that song. John 14:27 tells us not to let our heart be troubled or be afraid that Jesus gives us peace. We can be in situations where we are afraid and our hearts are troubled,  but with Jesus, all will be well with our soul! He will give you peace. 
John 14:27 - Peace I leave with you, My peace I give to you; not as the world gives do I give to you. Let not your heart be troubled, neither let it be afraid.
