Summary: God truly reveals His will when we begin to think as He thinks and live a pleasing life for the Lord.
Knowing God’s Will
(Romans 12:1-2; NKJV)
“I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.  And, do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.”
I. To understand God’s will for our lives we must OFFER OUR SACRAFICE unto Him.
The very first verse in this passage tells us we are to offer our bodies as a living sacrifice to God. A sacrifice was a very common part of worship among the Old Testament Israelites. Sacrifices were offered to God for a variety of reasons. These sacrifices were to contain blood. God required a surrogate death for man’s sinfulness.
(Luke 22:19-20) – “…He took bread, gave thanks and broke it, and gave it to them, saying, ‘This is My body which is given for you; do this in remembrance of Me.’  Likewise He also took the cup after supper, saying, ‘This cup is the new covenant in My blood, which is shed for you.’”
Is it any wonder, then, that the ultimate sacrifice which was Jesus Christ on the cross – on the brow of that awful hillside known as Golgotha – would naturally shed His precious blood for the atonement of sins? Because He offered His body as a sacrificial offering for the reconciliation between God the Father and all mankind, we too should offer our bodies as a sacrifice. The heavenly Father showered His mercy unto us; He offered upon us His eternal grace by giving us His Son, Jesus.
(Hebrews 7:25-27) – “…He is also able to save to the uttermost those who come to God through Him, since He always lives to make intercession for them.  For such a High Priest was fitting for us, who is holy, harmless, undefiled, separate from sinners, and has become higher than the heavens;  who does not need daily, as those high priests, to offer up sacrifices, first for His own sins and then for the people’s, for this He did once for all when He offered up Himself.”
There is no better sacrifice than for us to offer ourselves to God! This includes surrendering our lives, both spiritual and physical, to Almighty God, who is Creator over us all. From our text in Romans 12, the Apostle Paul calls it a “reasonable service.”
(Adam Clarke) – “We are not our own, we are the property of the Lord, by the right of creation and redemption; and, it would be as unreasonable as it would be wicked not to live to his glory, in strict obedience to his will…”
(Hebrews 13:20-21) – “…may the God of peace who brought up our Lord Jesus from the dead, that great Shepherd of the sheep, through the blood of the everlasting covenant,  make you complete in every good work to do His will, working in you what is well pleasing in His sight, through Jesus Christ, to whom be glory forever and ever…”
