Isaiah 65-66   God has declared what He will do for those who seek Him,  those who answer when He calls, those who seek to do what delights Him, instead of doing what He despises...

65:15b-16  "But My servants will be called by another name. Because he who is blessed in the earth shall be blessed by the God of truth;.... because the former troubles are forgotten, and because they are hidden from My sight!"

He will create " new heavens and a new earth; and the former things shall not be remembered or come to mind. But be glad in what I create; for behold, I create Jerusalem for rejoicing, and her people for gladness. And there will no longer be heard in her the voice of weeping and the sound of crying." 

Isaiah goes on to speak of the joy of this new life:
Infant mortality rate - 0
Old age- way past 100!
Building homes and living in them
Planting vineyards and enjoying the fruit.
None to plunder and steal.
Labor not in vain.
Children to enjoy.
".. no evil or harm in all My holy mountain." 

The Lord says, " It will come to pass that before they call, I will answer; and while they are speaking I will hear."   What a wonderful truth!  Our God hears us before we even begin to pray...

Chapter 66  The Lord says, " Heaven is My throne, and the earth is My footstool." 
There is coming a day when He will make a final judgement.  He will separate forever those who obey and follow Him and those who rebel and ignore Him.
He is looking for "this one"... "To him who is humble and contrite of spirit and who trembles at My word."  These are the only ones who can come to the holy mountain where He will:
".. extend peace to her like a river" ( v12)
".. I will comfort you;" (v13)  like a child is comforted by his mother.
"And the hand of the Lord shall be made known to His servants." (v14)

On the other hand.. those who make themselves enemies of God will be judged by fire and the sword.
Their corpses will burn with unquenchable fire and their "worm" shall not die.

Father in Heaven, even as we look to You to come again and take us to Your holy mountain.. we pray for those who have turned away from You.. those who are lost, imprisoned by their sin, and rebellious in their unbelief.  For some of those are ones we love.  How can we forget them?  Oh, God of mercy, bring them back to the truth! Hear this prayer, O God, and answer!  Bring salvation to my family members who are not yet saved.  Open their eyes, Lord!  Please call them to Jesus and open their ears to hear and their hearts to receive You.. I ask this in the Name of Jesus, according to Your Mighty Word. amen.
