Nullifying God's Grace.
It is impossible to live with a positive outlook and understanding of God's love if you live with a negative outlook and a misunderstanding of God's Grace.
However, it is possible to accept, apply and experience God's Love and Grace without fully understanding it.
But, it is not possible to accept, apply and experience God's Love and grace by the mixing of God's Grace (the new wine) with the God' Law (the old wine) in old wine skins and calling it Grace, because Grace stands alone and the mixing of Grace plus anything is not Grace.
When it comes to Grace...Grace plus Law equals ZERO Grace.
