Being Filled with Joy through Witnessing
John 15:5 I am the vine; you are the branches. He who abides in Me and I in him, he bears much fruit; for apart from Me you can do nothing. (11) These things I have spoken to you that My joy may be in you and that your joy may be made full.
The two happiest days in every believer’s life are the day he believes in the Lord and the day when, for the first time, he leads another person to Christ. The first one, of course, is a particularly happy day. However, the joy of leading another person to the Lord for the first time may be greater than the joy experienced on the day of his own salvation. Many Christians do not have much joy because they have never spoken anything for the Lord; they have never led a person to the Lord.
No tree will sprout without further growth. Likewise, no one can have God’s life without begetting more life. Those who never witness to sinners are probably in need of others witnessing to them. Those who have no desire or interest in leading others to repentance unto the Lord are probably in need of repentance themselves. Those who are silent for the Lord in front of others probably need to listen again to the voice of God’s gospel. No one can be so advanced that he no longer needs to save others. No one can advance to the degree that he no longer needs to witness to others. New believers need to learn to witness to others from the very beginning.
This is something we have to do for the rest of our lives.
