Dont you know that a little yeast affects the entire batch of dough?
and, again, that was a reference in the verse you cited to the sin of Pride.
And how can a Christian love homosexuals when god himself hates them?
https://net.bible.org/#!bible/Romans+1 So god made non believers into homosexuals? That really makes no sense to punish a sin with a sin.
Again, you appear not to have really read the verse you are citing.
Romans 1:
...18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, 19 because what may be known of God is manifest in them, for God has shown it to them. 20 For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, 21 because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. 22 Professing to be wise, they became fools, 23 and changed the glory of the incorruptible God into an image made like corruptible man—and birds and four-footed animals and creeping things.
24 Therefore God also gave them up to uncleanness, in the lusts of their hearts, to dishonor their bodies among themselves, 25 who exchanged the truth of God for the lie, and worshiped and served the creature rather than the Creator, who is blessed forever. Amen.
26 For this reason God gave them up to vile passions. For even their women exchanged the natural use for what is against nature. 27 Likewise also the men, leaving the natural use of the woman, burned in their lust for one another, men with men committing what is shameful, and receiving in themselves the penalty of their error which was due.
28 And even as they did not like to retain God in their knowledge, God gave them over to a debased mind, to do those things which are not fitting; 29 being filled with all unrighteousness, sexual immorality,[c] wickedness, covetousness, maliciousness; full of envy, murder, strife, deceit, evil-mindedness; they are whisperers, 30 backbiters, haters of God, violent, proud, boasters, inventors of evil things, disobedient to parents, 31 undiscerning, untrustworthy, unloving, unforgiving,[d] unmerciful; 32 who, knowing the righteous judgment of God, that those who practice such things are deserving of death, not only do the same but also approve of those who practice them...
God did not cause anyone to sin - for those who reject Him, their punishment is that they are allowed to sin. These people are leaving and God is letting them go. Nor does God hate them for doing so, but was willing to come and suffer and die for a chance to win back their hearts.
2 Peter 3:
...9 The Lord is not slack concerning His promise, as some men count slackness, but is longsuffering toward us, not willing that any should perish, but that all should come to repentance...
Homosexuals no less than adulterers, thieves, and murderers, us all.
Honest Christian's admit that they do not live up to the Christian standard.
right.
Which cannot be avoided since man lives in a world of sin right?
wrong. we make our own choices and are responsible for our sins.
