God has set us apart (sanctified us) for the purpose of growing us to become more like His Son. Through our faith in the Bible and the transforming work of the Holy Spirit, God changes our heart in order to change our character and actions. God's promise is that when we reach heaven, He will complete the process of making every believer like Jesus.
