"Forgive us this day our trespasses as we forgive others who tresspass against us". That is part of the Lords prayer Jesus recited to His Disciples you say you don't pray. How come you don't believe it applies to you?
That entire prayer was...
1- basically a model of various aspects within God's Prophesied aspect of His Will;
2- having to do with how they were to pray to the Father;
3- during Israel's hour of temptation;
4 - He was to have brought unto this world back then, prior to His Son's return;
5- but did not, because He had planned on interrupting that hour of His Wrath that Israel was then headed for;
6 - prior to His equally Prophesied, Promised delivery of them per His Covenant unto them.
7- which the Father had planned on temporarily interrupting; for a time.
Romans 9:19 Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will?
In essence, the accusation of Israel in Unbelief - "well, what is He waiting for now; He has proven He alone is sovereign; and that we are supposedly no better than the Gentiles- what else is left; what's He waiting for now?

At which point, Paul reminds Israel of another time in their long history of disobedience wherein God had reminded them that He works His power (His will) in His own times and seasons...
And how that: just as at other times within Unbelieving Israel's long, rebellious history, He had set apart those who Believed from those who had refused to - thus, His temporary delay of His outpouring of His wrath prior to His blessing Israel; so too now...
9:20 Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus? 9:21 Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour? 9:22 What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction: 9:23 And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory, 9:24 Even us, whom he hath called, not of the Jews only, but also of the Gentiles?
Paul then brings up more examples of times from within Unbelieving Israel's past wherein God had not only separated out Unbelieving from Believing Israel, but delayed pouring out His wrath prior to delivering them, but did something else, in the meantime.
All as a proof that He will pour out His wrarth at some point.
And that He will deliver Israel after that.
Romans 9:25 As he saith also in Osee, I will call them my people, which were not my people; and her beloved, which was not beloved. 9:26 And it shall come to pass, that in the place where it was said unto them, Ye are not my people; there shall they be called the children of the living God. 9:27 Esaias also crieth concerning Israel, Though the number of the children of Israel be as the sand of the sea, a remnant shall be saved: 9:28 For he will finish the work, and cut it short in righteousness: because a short work will the Lord make upon the earth. 9:29 And as Esaias said before, Except the Lord of Sabaoth had left us a seed, we had been as Sodoma, and been made like unto Gomorrha.
What has happened until then?
Why?
9:30 What shall we say then? That the Gentiles, which followed not after righteousness, have attained to righteousness, even the righteousness which is of faith. 9:31 But Israel, which followed after the law of righteousness, hath not attained to the law of righteousness. 9:32 Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone; 9:33 As it is written, Behold, I lay in Sion a stumblingstone and rock of offence: and whosoever believeth on him shall not be ashamed.
Paul will then expand upon that further, in Romans 10 and 11.
THAT is where much of what is instructed on in Matthew thru John is to be viewed from.
Matthew 10:18 And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles. 10:19 But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak. 10:20 For it is not ye that speak, but the Spirit of your Father which speaketh in you. 10:21 And the brother shall deliver up the brother to death, and the father the child: and the children shall rise up against their parents, and cause them to be put to death. 10:22 And ye shall be hated of all men for my name's sake: but he that endureth to the end shall be saved. 10:23 But when they persecute you in this city, flee ye into another: for verily I say unto you, Ye shall not have gone over the cities of Israel, till the Son of man be come.
Which was temporarily...interrupted.
Thus, Romans 11 ends on the very theme that Romans 9 began...
Romans 11:7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded.
11:25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. 11:26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 11:27 For this is my covenant unto them, when I shall take away their sins. 11:28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers' sakes. 11:29 For the gifts and calling of God are without repentance. 11:30 For as ye in times past have not believed God, yet have now obtained mercy through their unbelief: 11:31 Even so have these also now not believed, that through your mercy they also may obtain mercy. 11:32 For God hath concluded them all in unbelief, that he might have mercy upon all.
