"You yourselves are our letter, written on our hearts, known and read by everybody. You show that you are a letter from Christ, the result of our ministry, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts." -- 2 Corinthians 3:2-3
Are you pursuing a degree right now, or sometime in the near future? This is a good thing if it will provide you with the tools to better care for the souls of others. But never rest in the certificates on the wall as your credibility for ministry. The call of God, a servant's heart and lives changed are your recommendations. Your single and most valuable credential will always be the living letters of people changed for Jesus.
