Sing to the Lord , He has dealt bountifully twith us (Psalm 13:6)

Psalm 13:6, I will sing unto the LORD, because he hath dealt bountifully with me.

Cost :

In prayer faith is encouraged, through believing the heart is filled with joy; and this joy is expressed by the lips, in songs of praise to the Lord, ascribing the glory of salvation to him, and giving him thanks for every mercy and blessing of life.

Effect:

God will bless in both in a way of providence and grace, granting life and preserving it, and supporting with the comforts of it; blessing with spiritual blessings, and crowning with loving kindness and tender mercies; all which is generous and bountiful

Glory to God!
