Matthew 18:19 cut extra two words "God" after "whatever you ask ... " since these are assumed and not necessary here. The next phrase, "my Father" says this adequately.
Matthew 18:3 change wording. Eliminate "the way you think" after "change" because this is not in the original and limits the concept from "turn" to a mental process. What Jesus means is a lot more than that and is stated implicitly and should not be limited.
