Before unpacking this concept, I must explain that the concept of “common grace” must be viewed through a Biblical lens while keeping these two truths in mind:

• The complete and faultless sovereignty of God over everything.
  
• The complete depravity of every human being.

“Common grace is the term applied to those general blessings which God imparts to all men and women indiscriminately as He pleases, not only to His own people (Christians), but to all men and women, according to His own will”.

let's not take "Gods Will" and try to interpret outselves. God's will, or stance on such items as homosexuality and the meaning of marriage is CLEARLY stated in scripture.

The point is not what God approved here, is it? It is what he allows, namely freedom of conscience, and that his universal graces flow to just and unjust, good and evil, in the present dispensation, so to speak. The disciples wanted to sort the net. Christ enjoined otherwise, and said good and bad fish would exist together until the end. While in this parable, the "net" is the Gospel, it does suggest something of the Mind of Christ about human beings very limited ability to serve as arbiters of mercy and grace.
