God does not arbitrarily save you against your will. You must come to him on his terms. He has chosen to save everyone in Christ, but you must come to Christ. For it is with your heart that you believe and are justified, and it is with your mouth that you confess and are saved. You must confess with your mouths and believe in your heart that God raised Jesus from the dead.
True confession is more than uttering words.
Confession involves confessing and forsaking our sin. When the Ephesians came to Christ they openly confessed their evil deeds and burnt their sorcery bibles to embrace Jesus Christ. A number who had practiced sorcery brought their scrolls together and burned them publicly. When they calculated the value of the scrolls, the total came to fifty thousand drachmas. In this way the word of the Lord spread widely and grew in power.
