Galatians 3:18

For if the inheritance [of what was promised] is based on [observing] the Law [as these false teachers claim], it is no longer based on a promise; however, God granted it to Abraham [as a gift] by virtue of His promise.

Psalm 105:6-12


O you offspring of Abraham, His servant,
O you sons of Jacob, His chosen ones!

Psalm 105:42


For He remembered His holy word
To Abraham His servant;

Micah 7:18-20


Who is a God like You, who forgives wickedness
And passes over the rebellious acts of the remnant of His possession?
He does not retain His anger forever,
Because He [constantly] delights in mercy and lovingkindness.

Luke 1:54-55


“He has helped His servant Israel,
In remembrance of His mercy,

Luke 1:72-73


To show mercy [as He promised] to our fathers,
And to remember His holy covenant [the promised blessing],

Romans 4:13-16

For the promise to Abraham or to his descendants that he would be heir of the world was not through [observing the requirements of] the Law, but through the righteousness of faith.

Romans 8:17

And if [we are His] children, [then we are His] heirs also: heirs of God and fellow heirs with Christ [sharing His spiritual blessing and inheritance], if indeed we share in His suffering so that we may also share in His glory.

Galatians 2:21

I do not ignore or nullify the [gracious gift of the] grace of God [His amazing, unmerited favor], for if righteousness comes through [observing] the Law, then Christ died needlessly. [His suffering and death would have had no purpose whatsoever.]”

Galatians 3:10

For all who depend on the Law [seeking justification and salvation by obedience to the Law and the observance of rituals] are under a curse; for it is written, “Cursed (condemned to destruction) is everyone who does not abide by all things written in the book of the law, so as to practice them.”

Galatians 3:12

But the Law does not rest on or require faith [it has nothing to do with faith], but [instead, the Law] says, “He who practices them [the things prescribed by the Law] shall live by them [instead of faith].”

Galatians 3:16

Now the promises [in the covenants] were decreed to Abraham and to his seed. God does not say, “And to seeds (descendants, heirs),” as if [referring] to many [persons], but as to one, “And to your Seed,” who is [none other than] Christ.

Galatians 3:26

For you [who are born-again have been reborn from above—spiritually transformed, renewed, sanctified and] are all children of God [set apart for His purpose with full rights and privileges] through faith in Christ Jesus.

Galatians 3:29

And if you belong to Christ [if you are in Him], then you are Abraham’s descendants, and [spiritual] heirs according to [God’s] promise.

Hebrews 6:12-15

so that you will not be [spiritually] sluggish, but [will instead be] imitators of those who through faith [lean on God with absolute trust and confidence in Him and in His power] and by patient endurance [even when suffering] are [now] inheriting the promises.
