The just shall live by faith.
In Matthew 17:20, we read where Jesus had rebuked the demon from the boy that his disciples were unable to, that Jesus said to them: because of the littleness of your faith; for truly I say to you, if you have faith as a mustard seed, you shall say to this mountain, Move from here to there, and it shall move, and nothing shall be impossible to you.
Jesus asks nothing more of us then to believe and have faith. We are not told to live by rules and regulation. Just have faith that Jesus was born in Bethlehem, died on a cross for our sins, and rose again, and is alive forevermore.
Many times i have heard someone say that they are religious, but do not say they are Christians.
There is an old saying that religion vs Christian is only 18 inches from the head to the heart. With the head man thinks, but from the heart man loves.
If you are unsure of where you are, all your have to do is ask Jesus Christ to come into your heart. He is waiting for you to ask.
