Matthew 24:12 Cross References - AUV
James 4:1-4
1 Where do conflicts and fights among you come from? Do they not come from your [desire for] pleasures which produces inner conflict?
2 You people desire something and yet do not have it, [so] you murder [to get it]. You are envious [of what someone has] and [yet] are not able to obtain it, [so] you fight and quarrel [over it]. You do not have [what you want] because you do not ask [God for it].
3 [When] you do ask, you do not receive it, because you ask from wrong motives, [just] so you can satisfy your own pleasures.
4 You people who have become unfaithful to God, do you not know that being [intimate] friends with the world [of sin] means hostility toward God? Therefore, whoever determines to be an [intimate] friend of the world becomes an enemy of God.
James 5:1-6
1 Come on now, you rich people, cry and wail over the miseries that are coming upon you.
2 Your wealth has rotted and moths have eaten your clothing.
3 Your gold and silver have tarnished and their tarnish will be a testimony against you [i.e., you have hoarded your wealth instead of using it to benefit others], and they will devour your flesh as fire [i.e., your riches will ultimately consume you]. You have hoarded up your riches in these last days.
4 Look, the wages you have fraudulently refused to pay the workers who mowed your fields are crying out [against you]. And the cries of these harvest hands have reached the ears of the Lord of [heavenly] armies [i.e., Almighty God].
5 You people have basked in luxury [here] on earth and lived lives devoted to pleasure. You have fattened yourselves [as sacrificial oxen] for the day of slaughter.
6 You have condemned and murdered the righteous man [i.e., the innocent person, See verse 4] and he does not [even] resist you.
Revelation 2:4-5
4 “But, this is what I have against you, that you have forsaken your first love [i.e., love for Christ and His church].
5 So, remember where you have fallen from and repent [i.e., change your hearts and lives] and do the things you did at first [i.e., when you were first converted], or else I will come and remove your lampstand from its place [i.e., I will not permit the congregation to survive], unless you repent.
Revelation 2:10
10 Do not be afraid of the things you are about to suffer. [For] look, the devil is about to throw some of you into prison, so that you may be tested, and you will suffer persecution for ten days. [But], you should be faithful [to God] even to the point of dying [for Him], and I will give you the crown of [never ending] life.
