My Heart as an Acceptable Sacrifice

Only from You, Lord, do all blessings flow.  You have blessed me with so much, Lord.  I know that I can never do any deed that would be worthy enough to draw me closer to You.  The only acceptable offering to You is my heart.  I thank You and praise You for all You have done in my life.  I would like to offer my heart as a sacrifice to You.  I would like to give it as a mortal man to his eternal and omnipotent God.  This is all I have of worth.  

Lord, take my heart and mold me according to Your will.  Let me offer my sacrifice and let it be acceptable to You.  Give me strength so that I don’t falter in heart.  I need my heart unblemished for You.  Let my desire to have an acceptable sacrifice to You be strong and unwavering.
