Prayer to present yourself as a Holy Firstfruit to the Lord

Lord, I present my body as a living sacrifice of firstfruits, holy and acceptable unto You Rom 12:1. ‘But the fact is that Christ (the Messiah) has been raised from the dead, and He became the firstfruits of those who have fallen asleep [in death]’- 1 Corinthians 15:20. Transform me by the renewal of my mind that it is proven to me what is good, acceptable and perfect will of God during this fast- Rom 12:2. O God, You are My God, earnestly I seek You; my inner self thirsts for You; my flesh longs and is faint for You, in a dry and weary land where no water is- Ps 63:1.  Throughout this period of prayer and fasting, the Lord is my Strength and my Song, and He has become My Salvation- Ps 118:14
