When you commit your life to Jesus and He sets you free, you are truly free. Jesus set you free from sin, fear of death and your old life all by dying on the cross for you and being raised back up to life.
Sometimes you may doubt if you are truly changed and free. Whenever those thoughts come that cause you to doubt if something really happened, cast them down and say, “No, I’m a child of God. Jesus set me free and I’m free indeed.”
In Jesus you can know that your past is gone, your sins are completely removed and you are a new person in your spirit. You are truly free in Jesus.
