While I have some issues with Dobson I dont think think he is a man who lies. I also believe he is capable of giving a simple & clear presentation of the gospel.
For some people thats all it takes. A simple & clear presentation of the gospel, and then everything clicks together.
I don't think he's lying, I just think it's not his to announce to the world - it's Trump's. For him to then go on to say that Trump should be given time and space to "mature" as a Christian is pure hypocrisy, since he was the one who announced it in the first place.
