“If you want to do evil, science provides the most powerful weapons to do evil; but equally, if you want to do good, science puts into your hands the most powerful tools to do so. The trick is to want the right things, then science will provide you with the most effective methods of achieving them.”

Context: We hope that there will be nothing that conflicts with anybody's religion or faith. We would never say a person's religion is not effective.

Not that they are not effective, but do you want to help them become more effective?

Posed question: Are you mainly trying to show that there's no logical conflict even though there might be a methodological conflict?
