TMZ has learned ... Michael Lohan is showing up to Lindsay's court hearing on Friday -- but according to the actress' father non grata, he ain't going alone ... he's bringing some divine help.
Michael tells TMZ, he's rolling deep with some guy named Jay Koopman (left) -- an evangelical preacher who currently helps run youth ministries all over the world.
Michael tells us he wants Jay to lend Lindsay some heavenly advice in her time of need -- and hopefully get his derailed daughter back on track.
But here's the rub ... Dina Lohan also plans to show up in court ... and there's a restraining order requiring Michael to stay 100 yards away from her at all times.
