Week 3 Saturday — Walking with the Word
Saturday: Sanctified in Truth
Saturday: Sanctified in Truth
Introduction
Yesterday, the psalmist made a stunning claim: “It is good for me that I was afflicted, that I might learn your statutes.” He discovered that affliction can be a classroom where God’s Word teaches us what we could never learn in comfort. He declared that God’s Word was more valuable to him than thousands of gold and silver pieces.
But why does God’s Word have this transforming power? Why does it work in us differently than any other book or teaching? Today we turn to Jesus’ prayer on the night before His crucifixion, not just for His immediate disciples, but for all of us who would believe through their testimony. And in this prayer, Jesus reveals the secret: “Sanctify them in the truth; your word is truth.”
God’s Word doesn’t just inform us. It transforms us. It sets us apart. It prepares us for mission in a hostile world.
Scripture
¹⁴”I have given them your word, and the world has hated them because they are not of the world, just as I am not of the world. ¹⁵I do not ask that you take them out of the world, but that you keep them from the evil one. ¹⁶They are not of the world, just as I am not of the world. ¹⁷Sanctify them in the truth; your word is truth. ¹⁸As you sent me into the world, so I have sent them into the world. ¹⁹And for their sake I consecrate myself, that they also may be sanctified in truth.”
— John 17:14-19 (ESV)
Reflection
The Cost of the Word
Jesus begins with a sobering reality: “I have given them your word, and the world has hated them because they are not of the world” (v. 14). This echoes what the psalmist experienced, being smeared with lies, facing opposition, enduring affliction. When God’s Word inhabits and transforms us, it puts us at odds with the world.
We shouldn’t be surprised. Because of what we believe and our reliance on God’s Word and His Spirit (living like Jesus lived) we become aliens in this world, subject to persecution and rejection just like Jesus. The psalmist learned this. The disciples would experience it. And we face it too.
But notice what Jesus doesn’t pray for: “I do not ask that you take them out of the world, but that you keep them from the evil one” (v. 15). Jesus doesn’t pray for our removal from hostile environments. Just as He came to the world to save the world, His disciples have a mission to discharge, and to do it they must remain connected to the culture. He does, however, ask for protection from the evil one.
Sanctified by Truth
Here’s the key verse: “Sanctify them in the truth; your word is truth” (v. 17). The word “sanctify” means “to separate” or “to set apart,” usually for a specific purpose. In this context, it means “to dedicate” or “to consecrate.” What this means is that the believer is substantively changed by the working of God’s Word in his life, so much so that someone on the outside would call him a new person (the evidence of the new birth).
This is why the psalmist could say, “Before I was afflicted I went astray, but now I keep your word” (Psalm 119:67). The Word of God sanctified him. It set him apart. It changed him from the inside out.
This dramatic devotion results in separation from evil and dependence on God. God’s Word becomes our standard of truth personally for all of life. Not cultural trends. Not popular opinion. Not even our own feelings. God’s Word is truth, and it sanctifies us, makes us holy, sets us apart, prepares us for mission.
Sent Into the World
Jesus continues: “As you sent me into the world, so I have sent them into the world” (v. 18). We’re not sanctified so we can withdraw from the world. We’re sanctified so we can be sent into it. Just like Jesus.
And then comes this stunning statement: “For their sake I consecrate myself, that they also may be sanctified in truth” (v. 19). Jesus consecrated Himself. He set Himself apart for the cross so that we could be sanctified. His sacrifice makes our transformation possible. His obedience unto death purchases our freedom from sin and empowers us to live holy lives.
The psalmist experienced God’s goodness and learned through affliction. Jesus reveals the source of that goodness: the sanctifying power of God’s Word, made effective through His own consecration on the cross.
This is why God’s Word is more valuable than gold and silver. It’s not just information. It’s the instrument of our sanctification. It’s the truth that sets us apart, changes us from the inside out, and prepares us for mission in a world that desperately needs to see Jesus.
“Sanctify them in the truth; your word is truth.” — This is the way.
Prayer Prompts
Lord Jesus,
Thank You for giving us Your Word, even though it sets us apart from the world and sometimes brings opposition. Thank You for not praying that we’d be taken out of the world, but that we’d be kept from the evil one. Sanctify me in the truth—set me apart, change me from the inside out, make me holy. Let Your Word be the standard of truth for all of my life. Just as You consecrated Yourself for my sake, help me consecrate myself for Your mission. Send me into the world as You were sent, not to withdraw, but to witness. Not to hide, but to carry Your truth with courage and love. Amen.
Response
Reflect on these questions today:
“I have given them your word, and the world has hated them.” Have you experienced opposition or rejection because of your commitment to God’s Word? How did you respond? What would it look like to stand firm without withdrawing from the world?
“Sanctify them in the truth; your word is truth.” In what areas of your life is God’s Word currently sanctifying you, setting you apart, changing you from the inside out? Where are you resisting that transformation? What would full surrender to God’s sanctifying work look like?
“As you sent me into the world, so I have sent them into the world.” Do you see yourself as sent on mission in your workplace, neighborhood, family? If God’s Word has sanctified you and set you apart, where is He sending you to carry His truth this week?
