“To learn how you may serve Christ tomorrow, you must serve him today. Stir up your gifts and Christ’s call will be made clear.”
What is compelling you to lead or serve in ministry? Convenience would respond to that question with, “This is what I was trained to do.” Calling, on the other hand, would respond with, “This is what I was made to do.”
If you are leading or serving just because you love to do it, because you need to supplement your income, because of the notoriety, because you enjoy being up-front or because you are not trained to do anything else, then your compulsion might be out of convenience instead of calling.
Convenience fits well with a person’s plans or abilities; it is comfortable and readily accessible; it is suitable and favorable to one’s own needs and it is often accomplished with little effort.
Calling is a personal invitation from God to carry out a unique task; it is a strong inner impulse prompted by a conviction of divine influence and it often requires sacrifice.
• Convenience is a vocation; Calling is a ministry
• Convenience is a profession; Calling is a purpose
• Convenience is in the mean time; Calling is for a lifetime
• Convenience compares to; Calling is contented by
• Convenience focuses on withdrawals; Calling focuses on deposits
•Convenience is egoistic; Calling is altruistic
• Convenience is guarded; Calling is transparent
• Convenience is independent; Calling is collaborative
• Convenience is upwardly mobile; Calling is outwardly mobile
• Convenience is an occupation; Calling is a mission
Who can claim to possess such commitment to God and compassion to men, such knowledge of faith and ability to impart it, such maturity in godliness and wisdom in guiding others? Who but Jesus Christ, the great Shepherd of the sheep! He has the Spirit without measure and he gives that Spirit in full measure to those he calls.
Philippians 3:13-14 Brethren, I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, I press toward the goal for the prize of the upward call of God in Christ Jesus. (NKJV)
