If you declare with your mouth, “Jesus is Lord,” and believe in your heart that God raised him from the dead, you will be saved. For it is with your heart that you believe and are justified, and it is with your mouth that you profess your faith and are saved. Romans 10:9-10 (NIV)
What does “save” mean? God came to this earth in a human body and we call this person Jesus. He showed us how to live and He explained to us how we cannot adhere to the law but if we seek God with all of our heart and declare that “Jesus is Lord” we will be saved to have an eternity with Him.
Do you really believe? With your actions, mouth, heart, and mind?
