How do we know that God predestined us to be conformed to Christ's image?

The assurance that God has predestined believers to be conformed to the image of His Son is found in Romans 8:29. This passage expresses the conviction that God, in His eternal purpose and foreknowledge, chose a specific group of people to be transformed into the likeness of Christ. This transformation reflects God's ultimate goal for believers, which is to glorify His Son, making potential conformity to His image a guarantee for all whom He has chosen. Moreover, this predestination is not only a static decree but involves the entire salvation process—calling, justifying, and glorifying. As believers witness their gradual transformation through sanctification and the working of the Holy Spirit, they see the fulfillment of God's promise that they are indeed being made like Christ.
