This sign could be anywhere; not just on a United Methodist Church. So, its not about this PARTICULAR DENOMINATION, but the concept of church in general. I am sure those who put the sign up meant well, but face it, there sometimes is a lot of infighting with those who claim to follow Christ. Consider the following passage from the book of First Corinthians for example:
1Co 1:10 I appeal to you, brothers, by the name of our Lord Jesus Christ, that all of you agree and that there be no divisions among you, but that you be united in the same mind and the same judgment.
1Co 1:11 For it has been reported to me by Chloe's people that there is quarreling among you, my brothers.
1Co 1:12 What I mean is that each one of you says, "I follow Paul," or "I follow Apollos," or "I follow Cephas," or "I follow Christ."
1Co 1:13 Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul?
1Co 1:14 I thank God that I baptized none of you except Crispus and Gaius,
1Co 1:15 so that no one may say that you were baptized in my name.
1Co 1:16 (I did baptize also the household of Stephanas. Beyond that, I do not know whether I baptized anyone else.)
1Co 1:17 For Christ did not send me to baptize but to preach the gospel, and not with words of eloquent wisdom, lest the cross of Christ be emptied of its power.
1Co 1:18 For the word of the cross is folly to those who are perishing, but to us who are being saved it is the power of God.
1Co 1:19 For it is written, "I will destroy the wisdom of the wise, and the discernment of the discerning I will thwart."
1Co 1:20 Where is the one who is wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world?
1Co 1:21 For since, in the wisdom of God, the world did not know God through wisdom, it pleased God through the folly of what we preach to save those who believe.
1Co 1:22 For Jews demand signs and Greeks seek wisdom,
1Co 1:23 but we preach Christ crucified, a stumbling block to Jews and folly to Gentiles,
1Co 1:24 but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.
1Co 1:25 For the foolishness of God is wiser than men, and the weakness of God is stronger than men. ESV
The next time there is a problem in the church, think of this congregation. They had far more problems than any congregation I have ever seen, anywhere. Division, pride, sin of all sorts and yet God and the Apostle Paul still loved them; so much so that two books of the New Testament are devoted to them. Now the good news; they listened and changed their ways. They needed to refocus on Christ and stop sinning; if they can do it, I think just about anyone can. As far as this sign goes; "Please change me", today if possible!
