The "God must have a plan for you" lead-in is a common way to begin religious recruiting (often centered around a particular skill or gift someone has). I don't know about other denominations, but it's been a commonly-trained technique in the Church of Christ since at least the early 1980's.
And I'm not demeaning the approach at all. It's definitely smoother than saying: "Let me convert you to my religion" or "You're going to hell if you don't listen to me."
