Explain these Biblical quotes about helping the poor?

Amos -The rich and powerful of the land were the most guilty of oppression, as well as the foremost in idolatry. They were weary of the restraints of the sabbaths and the new moons, and wished them over, because no common work might be done therein. This is the character of many who are called Christians. The sabbath day and sabbath work are a burden to carnal hearts. It will either be profaned or be accounted a dull day. But can we spend our time better than in communion with God? When employed in religious services, they were thinking of marketings. They were weary of holy duties, because their worldly business stood still the while. Those are strangers to God, and enemies to themselves, who love market days better than sabbath days, who would rather be selling corn than worshipping God. They have no regard to man: those who have lost the savour of piety, will not long keep the sense of common honesty. They cheat those they deal with. They take advantage of their neighbour’s ignorance or necessity, in a traffic which nearly concerns the labouring poor. Could we witness the fraud and covetousness, which, in such numerous forms, render trading an abomination to the Lord, we should not wonder to see many dealers backward in the service of God. But he who thus despises the poor, reproaches his Maker; as it regards Him, rich and poor meet together. Riches that are got by the ruin of the poor, will bring ruin on those that get them. God will remember their sin against them. This speaks the case of such unjust, unmerciful men, to be miserable indeed, miserable for ever. There shall be terror and desolation every where. It shall come upon them when they little think of it. Thus uncertain are all our creature-comforts and enjoyments, even life itself; in the midst of life we are in death. What will be the wailing in the bitter day which follows sinful and sensual pleasures! Matthew -This is a description of the last judgment. It is as an explanation of the former parables. There is a judgment to come, in which every man shall be sentenced to a state of everlasting happiness, or misery. Christ shall come, not only in the glory of his Father, but in his own glory, as Mediator. The wicked and godly here dwell together, in the same cities, churches, families, and are not always to be known the one from the other; such are the weaknesses of saints, such the hypocrisies of sinners; and death takes both: but in that day they will be parted for ever. Jesus Christ is the great Shepherd; he will shortly distinguish between those that are his, and those that are not. All other distinctions will be done away; but the great one between saints and sinners, holy and unholy, will remain for ever. The happiness the saints shall possess is very great. It is a kingdom; the most valuable possession on earth; yet this is but a faint resemblance of the blessed state of the saints in heaven. It is a kingdom prepared. The Father provided it for them in the greatness of his wisdom and power; the Son purchased it for them; and the blessed Spirit, in preparing them for the kingdom, is preparing it for them. It is prepared for them: it is in all points adapted to the new nature of a sanctified soul. It is prepared from the foundation of the world. This happiness was for the saints, and they for it, from all eternity. They shall come and inherit it. What we inherit is not got by ourselves. It is God that makes heirs of heaven. We are not to suppose that acts of bounty will entitle to eternal happiness. Good works done for God’s sake, through Jesus Christ, are here noticed as marking the character of believers made holy by the Spirit of Christ, and as the effects of grace bestowed on those who do them. The wicked in this world were often called to come to Christ for life and rest, but they turned from his calls; and justly are those bid to depart from Christ, that would not come to him. Condemned sinners will in vain offer excuses. The punishment of the wicked will be an everlasting punishment; their state cannot be altered. Thus life and death, good and evil, the blessing and the curse, are set before us, that we may choose our way, and as our way so shall our end be. Luke 16- Here the spiritual things are represented, in a description of the different state of good and bad, in this world and in the other. We are not told that the rich man got his estate by fraud, or oppression; but Christ shows, that a man may have a great deal of the wealth, pomp, and pleasure of this world, yet perish for ever under God’s wrath and curse. The sin of this rich man was his providing for himself only. Here is a godly man, and one that will hereafter be happy for ever, in the depth of adversity and distress. It is often the lot of some of the dearest of God’s saints and servants to be greatly afflicted in this world. We are not told that the rich man did him any harm, but we do not find that he had any care for him. Here is the different condition of this go
