Self-estimation. Romans 12:3 All believers are members of the body of Christ and have been given spiritual gifts by God to give strength and joy to one another. Our conduct in the body is best expressed by love one to another. “By this shall all men know that ye are My disciples, if ye have one to another.” “We know we have passed from death unto life because we love the brethren.”
There is a problem in almost every human being that can hinder our spiritual worship. That is to have a wrong estimation of ourselves. An honest, accurate evaluation is based on knowing who we are in Christ if we are believers - not on comparing ourselves with other people. It is possible to claim we are so worthless that we aren't capable of worshipping or serving God. Usually that is a cop-out for not doing what we know we should. This is true though, if it were not for the grace of God in saving us and placing us in Christ.
Our self-worth as believers is based on our identity with Christ and being in Christ. By the holy standards of God, we are not capable of very much. In Christ we have been brought into the standards of perfect righteousness before God because we are seen in Him. We are able today and forever to worship and serve God according to His eternal standards through our Lord Jesus Christ.
Usually, the problem we have is that we way over-estimate ourselves. Pride is a basic temptation of most people. Pride of nationality, religion, face, success - even pride of grace makes us think we are important, and that attitude can stop what God wants to do through us. Our view of our importance is really only our own view. Other people could tell us humbling things if they were willing to. This opinion of ourselves is mentioned four times in this verse indicating that this has a lot to do with the renewing of our minds.
To evaluate one's self by the world's standard can either leave us with an exalted perception of our worth, or under-estimate what God says a person is worth. Much worldly value is placed on one because of that person's achievements, wealth, philanthropy or some other effect that person had on society. Each of us needs to evaluate ourselves honestly or we will be tempted to do what we are not equipped to do, or not do what God has gifted us to do. We are loved just as we are and because we are in Christ, there is value and capability to serve Him acceptably.
Faith is a gift from God that equips us to do His will. God has allotted a measure of faith for each person so that that person can fulfill whatever the Holy Spirit leads to do. The measure does not work based on making comparisons with the efforts of other people, but on the ability that God gives the individual. Therefore, it is important that I have the discernment of the role that God has given me to fill and fill it to the best of my ability.
“In accordance with the faith God has given you,” we have the power to accomplish in the local assembly as well as in the body, that which God desires. He gives us the power we need so no one can think they have more or less than others, because we are all different. God wants us to function in His work as He chooses, not as we or other people think.
Being constrained by the mercies of God, I am to be consecrated to divine service when I use what God has given in the way that He intended. That intelligent service is an act of worship to the One who has saved and called me. This first of a series of exhortations is a result of the transfiguration that comes from the renewing of the mind. The Lord Jesus Himself is the pattern of transfiguration [Mat.17:2]. The principle of transfiguration is given here in Romans 12:2 where we are told to be renewed in our minds. The power of transfiguration is the Holy Spirit according to 2nd Corinthians 3:13.
