Question:
Is there any sin considered worse than another sin or is a sin just a sin?

Answer:
In 1 John 5:16, 17, John says there is a sin unto death, and a sin not unto death, though what these are isn’t spelled out here. Ananias and Sapphira committed “a sin unto death” in Acts 5:1-11. It wasn’t clear to us though, what the passage in 1 John 5 meant exactly. There is also an unforgivable sin (Matthew 12:31, 32, Mark 3:29,30), to blaspheme against the Holy Ghost. The law in the Old Testament gave different degrees of punishment for different sins.

Today, the consequences of some sins are worse than others. The dead will be judged according to their works at the great white throne (Revelation 20:11-15). The works of believers will be tested and revealed as to what sort they are, and they will receive a reward or suffer loss accordingly (1 Corinthians 3:1015). Regardless of sins though, all those not in the book of life go to the lake of fire (Revelation 20:15), and all believers are saved (1 Corinthians 3:15).Because of this, it was pointed out that this question should not worry Christians too much, since we should not try to measure our sin or others’ sin. One sin makes us guilty of the whole law (James 2:10). Any sin disrupts our fellowship with the Father (though Christ our Advocate brings us back, 1 John 2:1), but no sin can change our position before God, since Christ is our Mediator (1 Timothy 2:5, 6).
