If that church, that pastor, those people, or that person who says they are Christian has done or do things that have caused you to not want to be a Christian or seek God, I am sorry, BUT...

You have made an idol and have put created things above the Creator. You have put God in the box with flawed, frail, and unfaithful humans.

Of course, you were failed by them. You were searching for the right thing in the wrong place.

DO NOT build the foundation of your faith on anything or anyone else but the LORD GOD JESUS CHRIST because He is ALWAYS FAITHFUL

Psalms 100:5 
For the Lord is good and his love endures forever; his faithfulness continues through all generations.

2 Timothy 2:13
if we are faithless, he remains faithful, for he cannot disown himself.
