Something to consider: Everywhere in the old testament sin was talked about. Every year everyone had to go the temple to make sacrifices for their sins. Jesus came to “take away our sins”; so we will never have to make sacrifices for them anymore. Jesus died for not some, but ALL our sins, past present and future. If that is truth why is it every time I turn on the Christian Radio station, Christian TV Station, all the men in the pulpit talk about is ‘sin’. Have they not read the Bible. WE ARE FORGIVEN! They talk about sin more than they did in the old testament.
If your foundation isn’t correct you CANNOT teach the word of God. When you read the Bible don’t do it with your mind; do it with your heart.
