God’s goal for you as a Christian is for you take the same form as His Son, Jesus Christ. The apostle Paul taught that before time began God chose to save believers so that they might come to have the same form as His Son (Romans 8:29).
This expresses the glorious goal of Christlikeness—of becoming like Jesus in our actions, in our behavior, in our thinking, motivations, compassions, love, and in our service to others. It’s everything that it means to be “transformed by the renewing of our minds” (Romans 12:2). In this we “prove what the will of God is, that which is good and acceptable and perfect.
Therefore I urge you, brethren, by the mercies of God,
to present your bodies a living and holy sacrifice,
acceptable to God,
which is your spiritual service of worship.
As we offer our bodies as living sacrifices on the altar of God, we are dead to sin and alive with Christ. So the living sacrifice of the believer doesn’t demand the destruction of the sacrifice as it did in the Old Testament. But it projects the full energy of life that is in Christ Jesus—the fullness of life, the abundance of life, all that it means to live the positive and dynamic life of Christ.
At the end of Romans chapter 11, the apostle Paul drops to his knees in praise and adoration for God. Before moving on his letter to the practical conclusions which flow from the grand and distinct doctrines of the Gospel, the apostle pauses to marvel at the ground which he had trekked. And looking back on the whole of Romans 1-11, Paul must exalt his Sovereign. God is worthy to be praised for God knows what He’s doing even when we do not. God is control of all of history even when we don’t get it. Therefore, Paul falls down before God and worships by bursting into a marvelous doxology.
Romans 11:28-32 shows us that God is control of all of all of history, even when He is disobeyed. The apostle Paul’s lifts up Israel as the prime example. Israel is now at enmity with God because they have rejected Jesus Christ. Nevertheless, God has made irrevocable promises of blessing which He will fulfill. Therefore, we should stand in awe of God because He designs and controls all of history to display His faithfulness to His promises and the glory of His mercy to sinners.
For I do not want you, brethren, to be uninformed of this mystery-- so that you will not be wise in your own estimation-- that a partial hardening has happened to Israel until the fullness of the Gentiles has come in; and so all Israel will be saved;
