E M Bounds defined consecration in the following way:
…..Consecration is the voluntary dedication of one’s self to God, an offering definitely made, and made without any reservation whatever. It is the setting apart of all we are, all we have, and all we expect to have or be, to God first of all. It is not so much the giving of ourselves to the church, or the mere engaging in some one line of church work. Almighty God is in view and he is the end of all consecration. It is a separation of one’s self to God, a devotion of all that he is and has to a sacred use….
Jesus prayed a prayer of consecration in the garden prior to the cross. Luke 22:42 Saying, Father, if You are willing, remove this cup from Me; yet not My will, but [ always] Yours be done. (Amplified Bible)
The Lord’s prayer also contains consecration. Luke 11:2 And He said to them, When you pray, say: Our Father Who is in heaven, hallowed be Your name, Your kingdom come. Your will be done [held holy and revered] on earth as it is in heaven. (Amplified Bible)
I’ve heard Christians mistakenly tack “if it be thy will” onto the end of every type of prayer. That isn’t what this means at all. Consecration is about preferring His will above ours – living in obedience to His word. So, we need to know His word and His direction for our daily lives as revealed by the Holy Spirit. Our prayers of supplication will then be in accordance with His will as it is revealed in His word. [Provision (give us this day our daily bread) and health ( by His wounds we were healed) – are His will.]
Obedience is God’s number one love language.
