Who is confused? The followers? Or the writer? If it's the followers, you'd choose the first. It means that these people are unclear about how or why they are doing this. If it's the writer, you'd choose the second. It means that the writer doesn't understand these people's way of doing this.

Hi Julie, These are called participial adjectives. the one with "ed" shows how someone feels and the one with "ing" describes how something or someone is. Now based on what you mean to express by the sentence, you need to choose the correct word.

Hi Julie :) both sentences are correct . to choose the correct participial adjective you should pay attention to who is confused and what is confusing .... the first sentence people follow the Lord Jesus in a confused way .the people who follow the Lord Jesus ,are confused. The second sentence those people follow the Lord Jesus in a confusing way. that action of following Lord Jesus by those people is confusing to you, and makes confused! I hope it make sense... let me know if you need more explanation

It actually depends. Both can be correct! The emphasis is slightly different. [1] If "confused" is used, it describes "those people". This emphasises that those people are confused in themselves, as in they personally are confused about the correct way to do things. [2] If "confusing" is used, it describes the way that they are following Jesus. This emphasises that their way is odd/puzzling for OTHERS who may not be able to understand their actions. They themselves may feel that they are doing things correctly, but their way confuses others. I would say the first one is more of a description and the second one is more of an evaluation/judgement. The difference is very slight, though, and they could concievably be interchanged, depending on what follows.
