Back to the basics.
You said you dislike Christians that just preach Christ crucified, but Paul says that is the way to evangelize. It isn't Christians that save you, it is Jesus Christ that saves you.
You say you don't know which denomination to go to to be saved, but you know it's Jesus you have to go to. Where's the excuse? God gives you the faith by His grace. You may not have that faith, but ask him for it. But this isn't a reason.
1 Corinthians 1
12Now this I say, that every one of you saith, I am of Paul; and I of Apollos; and I of Cephas; and I of Christ. 13Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul? 14I thank God that I baptized none of you, but Crispus and Gaius; 15Lest any should say that I had baptized in mine own name. 16And I baptized also the household of Stephanas: besides, I know not whether I baptized any other. 17For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.
18For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
19For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.
20Where is the wise? where is the scribe? where is the disputer of this world? hath not God made foolish the wisdom of this world? 21For 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. 22For the Jews require a sign, and the Greeks seek after wisdom: 23But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness; 24But unto them which are called, both Jews and Greeks, Christ the power of God, and the wisdom of God. 25Because the foolishness of God is wiser than men; and the weakness of God is stronger than men.
26For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called: 27But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; 28And base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are: 29That no flesh should glory in his presence. 30But of him are ye in Christ Jesus, who of God is made unto us wisdom, and righteousness, and sanctification, and redemption: 31That, according as it is written, He that glorieth, let him glory in the Lord.
And for the support of this Declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our lives, our fortunes and our sacred honor.
