In his excellent book Bible Doctrine, Wayne Grudem says, “Common grace is the grace of God by which he gives people innumerable blessings that are not part of salvation. The word common here means something that is common to all people and is not restricted to believers or to the elect only.” 

I came to Christ in a church that was Arminian, so that was naturally my early leaning. I went to a Bible college and seminary that were both middle of the road where neither hard core Calvinism nor Arminianism often surfaced in class, though on a continuum, some faculty would lean more toward one than the other.
