It's been quite a while since i first heard of Ken Ham & the ministry he's involved with; Answers in Genesis. If you're not familiar with this guy then you really should check him out.
He will be speaking in N. Ireland from August 10th to 13th in various locations around the province. Details here.
"If you find me short in things, impute that to my love of brevity. If you find me besides the truth in anything, impute that to my infirmity. But if you find anything here that serves to your furtherance and joy of the faith, impute that to the mercy of God bestowed on you and me."
