Roman’s 12:1 ESV
“I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.”
Because of the mercies of God, mercies being everything He has given us; eternal love, eternal grace, the Holy Spirit, everlasting peace, eternal joy, saving faith, comfort, strength, wisdom, hope, patience, kindness, honor, glory, righteousness, security, eternal life, forgiveness, reconciliation, justification, sanctification, freedom, intercession and much much more.
Paul says because of all these mercies and much more, we should give God every area of our life! Holding back nothing from Him, He deserves everything and available to deal with every area of our lives. It may sound scary to some to allow Him access to every area, but is actually an act of trust in Him.
