Secularism and Religion are both all about your personal performance. The Gospel is the performance of another applied to you.

A god of less wrath than the God of the Bible is necessarily a god of less love. His anger is a product of his love.

Unless we believe the gospel, we will be driven in all we do-whether obeying or disobeying-by pride ('self-love') or fear ('of damnation'). Apart from 'grateful remembering' of the gospel, all good works are done then for sinful motives. Mere moral effort may restrain the heart, but does not truly change the heart. Moral effort merely 'jury rigs' the evil of the heart to produce moral behavior out of self-interest. It is only a matter of time before such a thin tissue collapses.

Men, you'll never be a good groom to your wife unless you're first a good bride to Jesus.

If we give God things in hope that they'll earn us blessings, we're really not doing anything for him. It's for ourselves.

We get angry when we feel like God owes us a better life than we have.

I wouldn't venture to say which kind of sin is more prevalent. I wouldn't even want to try to characterize certain 'circles.'
