John Bunyan lists 7 ways we hold onto our sins
1. If possible, the soul that entertains sin will hide it so that it will not be discovered.
2. The soul that cannot hide its sin will excuse it and plead that it really is not such a bad thing
3. The soul that justifies its sin will seek to cover it with a good name (i.e. change what I call sin into something good)
4. If our convictions will not let us call our sin, sin, then we might flatter God that we will put it away from us in due time – (it’s no big deal)
5. If God pursues us and seeks to see if we have put away our sin – we will give up some part of it but keep the choicest part for ourselves
6. All sin must be abandoned or the soul will have no rest – so we might let our sins go with reluctance
7. If our sins that we have pout away should meet us again – we will court them and commit them in the dark
So sin goes in a circle – it starts in death & ends in death – We must deal sin a death-blow daily, over and over again, as John Owen says. Strike the root. Dig it us and burn it – and then keep on doing that. It is a never ending task – but sin mortified will help us see sin for what it is and help us deal with it as we ought.
