Giver,
I do dislike pursuing folks but it appears that you are not going to seek to engage me but a friend has led me to your post and so I begin. Our friend has suggested that you seem to be a Works/Salvation believer and in reading post, I agree.
When we study the Whole Bible, versus, the New Testament only we see that Father Abraham, for only one of many, was, though imperfect, saved by the grace of God. Abraham went so far astray that he gave up Sara to the King of Egypt to, he thought, preserve his life instead of trusting God to care for him.
In Romans 3:10 and 23 we find the key verses that explain to us that none of us are, even, worthy of life, let alone Heaven and yet when we look at the first three chapters of the Christian Bible we find that the Imperfect man, because he lusted for Eve more than he sought after God, He had created, was for fellowship and to return His love. No... this is not in the formation of the lines of text but rather, is there, between the lines and is taught by the Holy Spirit that indwells every Saved Man and Woman.
Now, when we read Matt. 22:1-14 we see a truth that just floors every legalist ever born, not all in the Kingdom are members of the Bride of the Christ. I suggest to you, after better than 23 years of study on the matter, that those that seek hard after Jesus are members of the Bride but those that tend to stumble, a bit more than the rest of us, are the Guests described. Now, I believe it important to notice one thing about a wedding... there will be my granddaughter and there will be her bo getting married but there will be about 150 of us guests there, this coming March. I like manor, I have presumed that there will be many of the guests at the wedding of the Bride in Heaven. In like manor, we understand that none will venture into Heaven further than the Great White Judgment location that are not saved. That makes the guests, saved.
God bless, my friend.
