We are called unto soul-winning... one needs to understand the mandate but judging is God's...

Professing your faith whilst deliberately omitting to take care of your family is an abomination according to scripture.

God says return unto Him as He has redeemed you (Isaiah 44:22 reads with Joel 2:12)

Faith and the Law are one because for one to have faith, one must adhere to the Law. In the old testament the laws were prescribed in terms of the books such as Exodus 20, the book of Leviticus. In the new testament the laws are prescribed in Matthew 22:37, 39.
