Charles and Frances Hunter have ministered side by side from the moment they were married on Jan. 1, 1970. With such rigorous ministry demands, just how have The Happy Hunters stayed so happy? Charisma asked them for the top five keys to a successful marriage.

"There's only one key," Charles says. "Death to self. When you're dead to self, you can't have bad attitudes. We've found that the only way to get rid of the 'I' feeling is to give up everything and let the fire of God fall--and it burns out the nature of the devil in you.

"If I [said something to Frances I shouldn't have said]," Charles continues, "I would have to look up and say, 'Jesus, that goes for You, too.' Because He lives in her, and whatever I say to her, I say to Jesus."

Frances believes one of the keys to a fulfilling marriage is for a couple to be completely committed to God. "Both of us love God with our heart, mind, body, soul and might. We're not interested in anything else. We only care about souls.

"We made a covenant before we were married that our marriage was going to work. We are so totally in harmony. We thoroughly enjoy each other. After 30 years, I still think he's the most interesting man in the world to talk to." Charles smiles. "She's fun to live with," he says. "She does some of the neatest little things. I just laugh. I wish I could tell you how much I love her."
