Faith is a gift and God gives different amounts in accordance to His purpose and plans for that individual; some have great faith and others have weak faith. We are respinsible to care for that gift, nourish it. Spiritual gifts are to be used prayerfully, diligently.
You don't seem to trust in the sovereignty of God. The Holy Spirit is in control and His plan is being accomplished. You seem to think man is screwing it up. You don't trust local Pastors as if God is not working through them. Some are better than others, some are not Spirit -filled; so you have to find one. We see many imperfections all around and so on the outside, no church is perfect! We might hear a few doctrines that are off and check that church off your list, then another and another until it seems none are worthy. That is an unfair judgment, a chopping block that leaves you all alone. So now you decide to set up your own church or blog and really teach everyone the real truth - because local churches don't have it! Don't deceive yourself and realize this: God factors in all our errors. The Body is a mixed bag of forgiven misfits outwardly, but spiritually, we are purified, as ONE. What you see is the sin and errors, false doctrines (not admitting that YOU have them). But which ones are false, yours or my mine, or just maybe most of Christianity is off kilter? No, God is right on schedule with His plan and the Church is right where He expected it to be.
I have never agreed 100% of the time with my Pastor, probably 98%: but he taught me so much and I am grateful had found the right church after going too many in my area. I've learned from dozens of scholars and don't believe I am 100% with any of them either, but close. You have to check out many before you find home. There is always one out there for you, God prepared one for you, or do you think He wants you to go off on your own? I have been to many churches once and would likely not return. But if there was only one in a fifty mile radius,, I'd go to that one and give and receive whatever I could.
