I wonder. Is it easier for those who have never before known how to enter, to accept the Good News, than for those who have heard the Good News but have latched onto (often from childhood, because that's when they were taught it) an incomplete or warped or even false version of it that still requires good works, or following "the Law" or whatever?
And why would people want to accept Jesus and get through the gate, and then spend the rest of their lives "trying to stay" by their own righteousness, in whatever form they think that involves?
There is a world of difference between doing good works because you love Jesus and love others with His love that is in you and flows out of you; and doing good works to try and keep your place in the Kingdom, as if what Jesus has done is really not sufficient.
How is it that we so quickly and easily become indifferent to Jesus? And turn to the Law and/or other substitutes to try to maintain our salvation and/or increase our righteousness? Or how can we just smugly accept our salvation, take it for granted, and then "get on with life" now that we feel safe in our fire insurance policy, or whatever? And not even be concerned about the safety of others?
