Most of "Man's current laws" are based on English Common Law, which is founded (for the most part) on the "Ten Commandments" and other religious-based commandments. You cannot legislate morality.

When man's decisions with regard to behavior step on another's rights, then it does become a matter of community concern and laws are passed to uphold those concerns.

It's not necessary me to forfeit man's current laws to follow the moral code of the 10 commandments. Scripture is clear that we are to submit to all governing authorities and laws UNLESS they directly conflict with God's Word. The more difficult part of God's Law is loving God with all your heart, mind and strength, followed closely by loving your neighbor as yourself.
It's extremely easy to act with love toward those you like and agree with, but requires the help of the Holy Spirit to love those who seem unlovable. Blessings.
