When it comes to being God's fellow workers, the first thing to realize is that we are not in control of the growth. We are called to plant. God gives the growth. God gets the credit. We cannot boast about the success that comes when the seeds are planted. We must be very cautious about taking too much credit for apparent success in the spiritual area.
A visitor to the Vatican was quite impressed with the beauty and power of the place. He asked Pope John XXIII this question: "How many people do you have working here?" With a twinkle in his eye, the pope replied, "About half of them." We must never get puffed up with ourselves in the spiritual realm. Only God produces growth. Real spiritual growth comes from God. We just plant seeds and try to nurture them as my farmer friends have taught me over the years.
