“Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord;” Acts 3:19
The word converted comes from the Greek word epistrepho which means to revert or turn. This word brings more clarity of what it means to repent. Salvation is a free gift, but you still have to do something to get it. I know saying something like that causes a lot of Christians to get nervous. However, you have to repent of your sins and turn away from them and turn to God if you want salvation. It is not different than if someone gives you a present. You have to reach out and take it from them. So if one is going to get saved, they have to humble themselves and turn to God to get it.
