Only God can persuade people – by that I mean only God can change people’s hearts, opinions, decisions. Whenever anyone turns to the lord, it is only because of the lord’s work in them.
However, we can be persuasive. And God can (and does) choose to use our attempts at being persuasive.
So we can aim to persuade, we can be persuasive in our manner, attitude and plans. But we must always stop at the thought that we actually brought about the persuasion that is due to the work of the spirit.
