Isaiah 59:22
“‘This is My Covenant with them,’ says the Lord. ‘My Spirit Who is upon you, and My words which I have put into your mouth, shall not depart out of your mouth nor out of the mouth of your seed nor out of the mouth of your seed’s seed,’ says the Lord, ‘from henceforth and for ever!’”

Gen 17:7 And I will establish My covenant between Me and you and your descendants after you in their generations, for an everlasting covenant, to be God to you and your descendants after you.
Heb 11:1–3 Now faith is the substance of things hoped for, the evidence of things not seen. 2 For by it the elders obtained a good testimony.
3 By faith we understand that the worlds were framed by the word of God, so that the things which are seen were not made of things which are visible.

Do you have faith in these promises? Do you really?

Luke 18 8 I tell you that He will avenge them speedily. Nevertheless, when the Son of Man comes, will He really find faith on the earth?”
The New King James Version (Nashville: Thomas Nelson, 1982), Lk 18:8.
