Some people just are not master communicators. If they show a life reborn in the spirit and a sincere desire to live for God I am not going to criticize how they express how they got there. If they say that they 'accepted' Jesus as part of their testimony or even tell others to 'accept' Jesus as part of spreading the gospel, I am not going to knock it. I think it's the doing of those things that matters to God- Not how strong our voice is, how perfectly structured, how theologically correct, or precisely delivered our words... But that our hearts, now being changed by the work of the Holy spirit, desire to see another heart changed.
Sometimes, when things get down to semantics, I know that we have way too much time on our hands.
