Revelation 21:19

19 The foundation [stones] of the wall of the city were ornamented with all of the precious stones. The first foundation [stone] was jasper, the second sapphire, the third chalcedony (or white agate), the fourth emerald,

• As we have studied already jasper has several colors in it. Jesus sacrifice has allowed people from every tribe, tongue, and nation to be His Bride and the wall, or God’s protection, and our Father's protection is for all people. The foundation of our Father’s protection and mercy is that it is for all people, not just a select few.
• Another powerful truth about Jasper is that it is plentiful. The foundation of eternities wall is plentiful; people from every tribe, nation, and tongue, a number that no one could count, and as the sands of the sea. These are all terms that we have studied about eternity and the guests that are allowed to be there with the Bride. The Bride may be few, but the guests are plentiful.  
• For God has consigned (penned up) all men to disobedience, only that He may have mercy on them all [alike]. Romans 11:32
• When Moses saw the works of our Father he saw sapphire.
• And they saw the God of Israel [that is, a convincing manifestation of His presence], and under His feet it was like pavement of bright sapphire stone, like the very heavens in clearness. Exodus 24:10
• Sapphire is mainly blue, but it may also have green, grey, pink, and violet colors in it. Sapphire is a very hard stone and it stands for excellence and beauty. All things become new in eternity and all of the former things that caused death and pain are gone. This is a foundation of our protection in eternity.
• Death and Hades will have been thrown into the Lake of Fire, Revelation 20:13
• All things will be new when our Father comes to dwell with men, Revelation 21:5.
• Chalcedony will actually brighten when it is under the sunlight. In eternity the glory of the New Jerusalem will be that life is lived for others and not for ourselves.
• He who is greatest among you shall be your servant. Matthew 23:11
• Emerald represents the purest faith and in eternity Jesus will be the perfect Author and Finisher of faith.
• Looking away [from all that will distract] to Jesus, Who is the Leader and the Source of our faith [giving the first incentive for our belief] and is also its Finisher [bringing it to maturity and perfection]. He, for the joy [of obtaining the prize] that was set before Him, endured the cross, despising and ignoring the shame, and is now seated at the right hand of the throne of God. Hebrews 12:2
• Therefore He is able also to save to the uttermost (completely, perfectly, finally, and for all time and eternity) those who come to God through Him, since He is always living to make petition to God and intercede with Him and intervene for them. Hebrews 7:25
• In eternity everyone who is there will have come to our Father because of what Jesus has done for us all. His sacrifice will cause every knee to bow and every tongue to confess the Truth that will set us all free. Jesus will cause us all to live in the faith of love and love seeks out the well being of others.
