Be still my soul

From my today's Devotional reading "Streams in the Desert":

O troubled soul, beneath the rod,
You Father speaks, be still, be still;
Learn to be silent unto God,
And let Him mold you to His will.

O praying soul, be still, be still,
He cannot break His promised Word;
Sink down into His blessed will,
And wait in patience on the Lord.

O waiting soul, be still, be strong,
And though He tarry, trust and wait;
Doubt not, He will not wait too long,
Fear not, He will not come too late.

Lord, please, help me to be still and know that You are God.
