How do you know that you are saved? God will save you His way, not your way. Read Matthew 7:21-23.What that means is that there is only one way to be saved. It is not enough to believe in God with your mind, you have to believe it with your heart! That is completely Biblical! It says so in Romans 10:9:
That if you confess with your mouth the Lord Jesus and believe in your heart that God has raised him from the dead, you will be saved.
There is only one way to be saved, and is through believe in Jesus Christ and a changed life – pointing to a time in your life where there has been a complete life transformation. By saying a time in your life, I don’t mean a specific day and time, but just a general time period. The Bible does not say that we have to know a specific date or time. If you haven’t had a complete life change, if you went back to your old habits after “giving” your life to Christ, then I have news for you – you are not saved!
