An appropriate birthday wish for a pastor is "Some see a birthday as a reminder of one less year to live. Believers see a birthday as one year closer to eternity," as reported by Birthday Quote. A special Bible verse or personal anecdote may also be included.
Another birthday greeting for a pastor is "I am so happy that God led me to your church. I pray for the Lords continued blessings upon you. Happy birthday!," as stated by Brandon Gaille.
"I join with you in your birthday celebration. I hope you have a special time, and I pray you'll always know how special you are to me and to the Lord" is an excellent birthday wish to remind a pastor of how important he is in an individual's life.
