1 Peter 2:12 Having your conversation honest among the Gentiles: that, whereas they speak against you as evildoers, they may by your good works, which they shall behold, glorify God in the day of visitation.
1 Peter 3:1 Likewise, ye wives, be in subjection to your own husbands; that, if any obey not the word, they also may without the word be won by the conversation of the wives; 2 While they behold your chaste conversation coupled with fear.
And a negative example:
1 Corinthians 10:31So whether you eat or drink or whatever you do, do it all for the glory of God. 32 Do not cause anyone to stumble, whether Jews, Greeks or the church of God--
followed by an interesting positive....
33 even as I try to please everybody in every way. For I am not seeking my own good but the good of many, so that they may be saved. 11:1 Follow my example, as I follow the example of Christ.
Matt. 9:10ff While Jesus was having dinner at Matthew's house, many tax collectors and "sinners" came and ate with him and his disciples. 11 When the Pharisees saw this, they asked his disciples, "Why does your teacher eat with tax collectors and 'sinners'?" 12 On hearing this, Jesus said, "It is not the healthy who need a doctor, but the sick. 13 But go and learn what this means: 'I desire mercy, not sacrifice.' For I have not come to call the righteous, but sinners."
Seeing that one does not want to waste his time reading "irrelevant " scripture,"
Are you asserting that all Scripture is relevant to every situation? I know you're not. You needn't respond to this point.
Where does any of that scripture say seeing your good works saves anyone? You are reading into the text something that is not there .
These commands like all of the admonitions had nothing to do with "saving anyone ".They did have to do with God being glorified in HIS people .
Rom 2:19 And art confident that thou thyself art a guide of the blind, a light of them which are in darkness,
Rom 2:20 An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.
Rom 2:21 Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?
Rom 2:22 Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?
Rom 2:23 Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
Rom 2:24 For the name of God is blasphemed among the Gentiles through you, as it is written.
As was said to David
2Sa 12:14 Howbeit, because by this deed thou hast given great occasion to the enemies of the LORD to blaspheme, the child also [that is] born unto thee shall surely die.
1Ti 6:1 Let as many servants as are under the yoke count their own masters worthy of all honour, that the name of God and [his] doctrine be not blasphemed.
Our sin and our walk either give God glory or blaspheme His name in the mouth of the heathens
For a man to think one is saved by HIS walk is contrary to the word of God , that says clearly that it is the word of God , that brings one to faith , not our feeble works that bring a man to faith and salvation.
Rom 10:17 So then faith [cometh] by hearing, and hearing by the word of God.
1Cr 1:21 For after that in the wisdom of God the world by wisdom knew not God, it pleased God by the foolishness of preaching to save them that believe.
1Pe 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
Rom 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
Eph 1:13 In whom ye also [trusted], after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: [it is] the gift of God:
Eph 2:9 Not of works, lest any man should boast.
2Cr 4:3 But if our gospel be hid, it is hid to them that are lost:
God is jealous for His name , salvation is all about God, not one with about the work or behavior of men. That is what the gospel teaches .
