"I beseech you therefore, brethren, by the mercies of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service." Rom 12:1
The first thing for all of us to do is to present ourselves to God as alive from the dead, and our bodies as living sacrifices. The path of blessedness can be entered by no other gate. It is only as we refuse to be conformed to this world, and yield ourselves to be transformed by the free entrance of the Holy Spirit into our minds, that we can learn all that God will do for us. We are nothing; He is all. And He is prepared to be and do all things in us, if only we will He open to Him as the land lies open to the summer sun.
Those who really live the yielded life, do not need to ascertain God's Will by signs. They recognize it by the whisper of His voice and the touch of His hand. It is as we refuse to be moulded by the world, and give ourselves up to the transfiguring Spirit of God, that we prove what is His good, acceptable, and perfect will. But more than that, we begin to live for others, and draw by faith from the fullness of God, that we may minister to them aright.
First, we understand what the Will of God is; then we present our bodies that it may fulfil itself through us; then we discover that it means goodwill to men, and we become the happy channels of heavenly ministry to those around us in one of the spheres enumerated in Rom 12:6-8 of this chapter. It is impossible to cherish jealousy, because the Head may use this member or that; it is equally impossible to be proud, because we have nothing that we have not received. Let us always remember that each has a special ministry to fulfil, and that we shall find in our daily lot the opportunity of fulfilling it. How many resemble the landowner of the Eastern story, who sold his property in order to go in search of diamonds, and lo! The man who purchased his property found it full of diamonds. Indeed it was the famous Golconda region. In the dally drudgery of life you will find your heavenly opportunity. How many who are pining for a great mission, will never be permitted to enter it, because they despise the low and narrow door of humble service to those in their immediate neighbourhood.
But we can never realize these divine ideals of service merely by an external obedience. We must be constrained by a holy love to our Lord and to one another. What a despair these ideals would be apart from the Holy Spirit. That holy love comes from Him.
