Which is the greatest sin before the Lord

I know many people always ask this question and sometimes they make some answers that do not really exist

I know the Bible writes very well that there is no sin greater or smaller before the Lord but I will tell you today that the most detestable sin before God is Sexual sin ask me how and I will tell you that it's only this sin that you sin within your body the rest are done outside the body and don't you know that your body is the Holy temple of the LORD.?
