The Bride

Revelation 21:2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.

Here is an example in the Bible that draws an analogy between the kingdom of heaven and a bride.

Revelation 21 King James Version

21 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.

2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.

3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. 4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.

1 Samuel 17:25 And the men of Israel said, Have ye seen this man that is come up? surely to defy Israel is he come up: and it shall be, that the man who killeth him, the king will enrich him with great riches, and will give him his daughter, and make his father's house free in Israel. (as a bride).

One can take the analogy to mean that if David can kill Goliath, he will recieve the daughter as a bride, and the bride symbolizes the kingdom of heaven. Goliath, the giant symbolizes your greatest enemy, your greatest material desire, be it sex, money, more possessions. And once again, when you kill your desires you will get heaven.

Uncircumcised means materialistic … ?
1 Samuel 17:26 And David spake to the men that stood by him, saying, What shall be done to the man that killeth this Philistine, and taketh away the reproach from Israel? for who is this uncircumcised Philistine, that he should defy the armies of the living God?
