So, are you affirming that your belief is that blessings from God can ONLY come "through the mormon church"?
I think that pretty much says it all.
Can you provide a BIBLICAL source for that, ALL blessings must come through the/a church?
All blessings? No, good weather is a blessing from God, and it comes to the wicked and the faithful alike. Same with many other things. Temple blessings however can only be obtained through the priesthood of God that was restored to the church.
