For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them (Ephesians 2:8-10).
Being found in Christ, means that the believer does not depend on his own righteousness and obedience to ‘get right’ with God, instead, his righteousness and obedience flow from his having ‘been made right’ with God.
The ultimate assurance for the Christian is that his eternal soul is secure in the person and work of Jesus Christ. We cannot add to this, no matter how good we are, nor can we take away from it, no matter how much we mess up! We have been saved- set apart for God and sealed for all eternity- by grace, through faith, in Jesus Christ.
Positional- or judicial- holiness in Christ always precedes, and fuels, growth in personal holiness! Our good works- not matter how sincere- can never bring about right standing before God, but right standing- by grace through faith in Jesus Christ- should always result in good works! We have been made right with God, and so we are called to live right before God, not to earn our standing, not to keep our standing, but because of our standing!
