John 17:13–19 “I am coming to you now, but I say these things while I am still in the world, so that they may have the full measure of my joy within them. I have given them your word and the world has hated them, for they are not of the world any more than I am of the world. My prayer is not that you take them out of the world but that you protect them from the evil one. They are not of the world, even as I am not of it. Sanctify them by the truth; your word is truth. As you sent me into the world, I have sent them into the world. For them I sanctify myself, that they too may be truly sanctified.

Jesus wants you to have joy! Isn’t that a comforting thought? “…so that they may have the full measure of my joy within them.” Our joy in Christ is not necessarily happiness, but it is certainty. I know that in any and all circumstances, no matter how bad a day I am having, no matter how bad I feel, I have the assurance of forgiven sin and life everlasting. That gives me joy that lives deep inside of me.

I don’t base this on how I feel or how much effort I have put into trying to be good. My joy is based on what God has told me in His Word. Even though this world will hate us for being the followers of Jesus, we know this world is not all there is. Jesus went to prepare our eternal home for our arrival, a place for us.

Before leaving, He prayed, “Sanctify them by the truth; your word is truth.” To sanctify means to make holy. We are made holy by the truth which comes from God’s Word. Not “you have your truth and I have mine,” but THE truth. God’s Word. Where true joy is found.

Psalm 16:11 You have made known to me the path of life; you will fill me with joy in your presence, with eternal pleasures at your right hand.

The joy comes when you have heard and believed that Jesus came into the world to save you. He paid for your sin. He defeated death for you. He wants you to have the benefit of all He did and earned. God has rescued you.

John 14:6 Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me.

We are called to share that truth, and therefore that joy, with the world.
