Uh, speaking purely as a husband....do not goad, prod or force him at all. Let him know..even with a few butterfly kisses, that you have his best interest at heart and will be praying and making it a matter of concern between you and GOD for him to not procrastinate his role, using his spiritual gifts. Leave it at that..and, perhaps in a couple of weeks or so, give him a hint, nothing more....period...HE has to do it willingly, openly or not at all. When my dad was in seminary, I remember him coming home one night and saying to me.."Wow, there are a lot of Mama called and Daddy sent preachers out there!" IF you catch my drift, he has to have his own gumption, with your support, which obvious, he already has.
