Galatians 3:15-18

To speak in terms of human relations, brethren, [if] even a man makes a last will and testament (a merely human covenant), no one sets it aside or makes it void or adds to it when once it has been drawn up and signed (ratified, confirmed). Now the promises (covenants, agreements) were decreed and made to Abraham and his Seed (his Offspring, his Heir). He [God] does not say, And to seeds (descendants, heirs), as if referring to many persons, but, And to your Seed (your Descendant, your Heir), obviously referring to one individual, Who is [none other than] Christ (the Messiah). This is my argument: The Law, which began 430 years after the covenant [concerning the coming Messiah], does not and cannot annul the covenant previously established (ratified) by God, so as to abolish the promise and make it void. For if the inheritance [of the promise depends on observing] the Law [as these false teachers would like you to believe], it no longer [depends] on the promise; however, God gave it to Abraham [as a free gift solely] by virtue of His promise. Galatians 3:15-18

Now faith is the assurance (the confirmation, the title deed) of the things [we] hope for, being the proof of things [we] do not see and the conviction of their reality [faith perceiving as real fact what is not revealed to the senses]. For by [faith—trust and holy fervor born of faith] the men of old had divine testimony borne to them and obtained a good report. By faith we understand that the worlds [during the successive ages] were framed (fashioned, put in order, and equipped for their intended purpose) by the word of God, so that what we see was not made out of things which are visible. Hebrews 11:1-3

So the other disciples kept telling him, We have seen the Lord! But he said to them, Unless I see in His hands the marks made by the nails and put my finger into the nail prints, and put my hand into His side, I will never believe [it].Eight days later His disciples were again in the house, and Thomas was with them. Jesus came, though they were behind closed doors, and stood among them and said, Peace to you! Then He said to Thomas, Reach out your finger here, and see My hands; and put out your hand and place [it] in My side. Do not be faithless and incredulous, but [stop your unbelief and] believe! John 20:25-27

[It is He] Who has qualified us [making us to be fit and worthy and sufficient] as ministers and dispensers of a new covenant [of salvation through Christ], not [ministers] of the letter (of legally written code) but of the Spirit; for the code [of the Law] kills, but the [Holy] Spirit makes alive. Now if the dispensation of death engraved in letters on stone [the ministration of the Law], was inaugurated with such glory and splendor that the Israelites were not able to look steadily at the face of Moses because of its brilliance, [a glory] that was to fade and pass away, Why should not the dispensation of the Spirit [this spiritual ministry whose task it is to cause men to obtain and be governed by the Holy Spirit] be attended with much greater and more splendid glory? For if the service that condemns [the ministration of doom] had glory, how infinitely more abounding in splendor and glory must be the service that makes righteous [the ministry that produces and fosters righteous living and right standing with God]! Indeed, in view of this fact, what once had splendor [the glory of the Law in the face of Moses] has come to have no splendor at all, because of the overwhelming glory that exceeds and excels it [the glory of the Gospel in the face of Jesus Christ]. For if that which was but passing and fading away came with splendor, how much more must that which remains and is permanent abide in glory and splendor! 2 Corinthians 3:6-11
