I think it is easy to get muddled up by well meaning believers who want to begin making themselves out as sole stewards of Christ’s saving spirit just because they have had a spiritual success in their own lives that they do not see in their immediate environs. C. S. Lewis’ essays have proven useful to me in this regard, especially where Lewis commented that once he was versed well in “mere Christianity” his quotations from various Christian sources of stature kept getting misattributed, such as John Bunyan being mistaken for Roman Catholicism. This is true... I’ve had more than one Roman Catholic tell me that I have to be some kind of unofficial Catholic. I don’t claim anything but to be a Christian who has learned from a myriad of channels of God’s spirit.
Yet, Jesus told Thomas, Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe. Thomas said to him, My Lord and my God! Then Jesus told him, Because you have seen me, you have believed; blessed are those who have not seen and yet have believed. (John 20:27-29)
In Christianity, it's not "seeing is believing, it's believing is seeing"!
