You don't need to preach to me. Being a Christian doesn't mean being perfect. Being a Christian is about having faith in Christ and having a repentant heart; it means trying. I've long repented of adultery and stayed away from the Eucharist for nearly a year. I fall to the temptation of inappropriate contentography maybe twice a month, and I struggle with alcoholism. These things don't exclude me from being a Christian. My hope is in Jesus. My sins disgust me. Quite frankly you have a poor understanding of what it means to be a Christian.
Luke 18
9 He also told this parable to some who trusted in themselves that they were righteous, and treated others with contempt: 10 “Two men went up into the temple to pray, one a Pharisee and the other a tax collector. 11 The Pharisee, standing by himself, prayed[a] thus: ‘God, I thank you that I am not like other men, extortioners, unjust, adulterers, or even like this tax collector. 12 I fast twice a week; I give tithes of all that I get.’ 13 But the tax collector, standing far off, would not even lift up his eyes to heaven, but beat his breast, saying, ‘God, be merciful to me, a sinner!’ 14 I tell you, this man went down to his house justified, rather than the other. For everyone who exalts himself will be humbled, but the one who humbles himself will be exalted.”
Romans 3
21 But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— 22 the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction: 23 for all have sinned and fall short of the glory of God, 24 and are justified by his grace as a gift, through the redemption that is in Christ Jesus, 25 whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins. 26 It was to show his righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus.
Romans 7
15 For I do not understand my own actions. For I do not do what I want, but I do the very thing I hate.
1 Timothy
15 This is a faithful saying and worthy of all acceptance, that Christ Jesus came into the world to save sinners, of whom I am chief.
1 John
8 If we say we have no sin, we deceive ourselves, and the truth is not in us. 9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. 10 If we say we have not sinned, we make him a liar, and his word is not in us.
Also, Google is a thing. It holds a lot of information that is accessible within minutes. Dr. Chettawut's page is right there after you spend 15 seconds typing in key words; and no, the pictures are not rare.
