Joy naturally flows from knowing Christ, and it draws others to Him.

What was from the beginning, what we have heard, what we have seen with our eyes, what we have looked at and touched with our hands, concerning the Word of Life–and the life was manifested, and we have seen and testify and proclaim to you the eternal life, which was with the Father and was manifested to us–what we have seen and heard we proclaim to you also, so that you too may have fellowship with us; and indeed our fellowship is with the Father, and with His Son Jesus Christ. These things we write, so that our joy may be made complete. 1 John 1:1-4

Jesus calls us to be His witnesses (Acts 1:8). On hearing this, some Christians worry that they need special skills or charisma in order to explain the good news to someone else. Yet to bear witness is not merely to share the plan of salvation. The phrase literally means “to know by personal experience” or “testify to.” In today’s passage, John wrote that he was sharing things he’d experienced firsthand. What he was saying is this: “I’m full of joy because of the experience of knowing Jesus, and I want you to share in that joy.”

When you’re in love with someone, you are excited about the relationship and enjoy spending time together. Likewise, when you’re in love with Jesus, you can’t keep to yourself the joy that comes from knowing Him—it just spills over, bearing witness and strengthening other believers. People around you will pick up on the deep, genuine gladness in your heart that goes beyond natural happiness. And some who don’t yet know the Lord will find themselves hungering for the joy you have.

Witnessing is not a matter of eloquence or talent; it’s an overflow of a relationship with Jesus. As you allow the Holy Spirit to increasingly express His life and power through you, contagious joy will be the fruit of His indwelling presence.
