This is the first part of the verse; it’s Jesus speaking, “I have revealed Your name” (John 17:6a, BSB). Colossians 1:15 tells us that Jesus is the visible image of the invisible God.
We look at Jesus and see God. He revealed, or manifested, God’s name, to those who saw and experienced being with Jesus. God’s name is His nature, His character and authority. We can look at Jesus to see who God is. We see Jesus speaking to the wind and controlling it: God’s authority over nature. We see Him raise the widow’s son from the dead because He was moved with compassion: His authority and character. He heals and delivers everyone, even when it makes life harder for Himself. The lepers are kept out of town because of their disease. Jesus heals them and commands them to tell no one, but they do, and then Jesus is the one who has to stay out of town because of the crowds. He feeds the hungry, moved with compassion. While Jesus says He was born to be king, He also says that He came to serve, not to be served.
When the disciples want to call down fire from heaven, Jesus rebukes them. God does not delight in wrath. He delights in mercy. Jesus would have been just in picking up a stone, but He forgave the woman caught in sin. God is gracious and compassionate. God is healer and provider. God is loving and merciful. God is forgiving and kind. Jesus spent His time with sinners-turned-disciples. At the same time, He was holy and kept Himself apart. He didn’t allow anyone to move Him. He was compelled by love, love for His Father that looked like obedience, and love for others, that showed the Father’s heart for those He created. When you read in the Old Testament about disasters brought on God’s people, know the aching heart of God who does not delight in the death of the wicked, but desires all to come to repentance.
Remember Jesus touching the untouchable and demonstrating His divinity to all who would have eyes to see. Some just refused to believe. Of course, Jesus has the same name as God the Father, the same character, nature, and authority. God has always been revealing Himself to us. “I, the LORD, did everything I could to teach you about my faithfulness” (Micah 6:5b, NLT). He has shown Himself to us. He wants us to know Him as good, loving, merciful, trustworthy, faithful.
He has always shown Himself faithful. “Who is a God like you, pardoning iniquity and passing over transgression for the remnant of his inheritance? He does not retain his anger forever, because he delights in steadfast love” (Micah 7:18, ESV). The blood of Christ means our sins can be forgiven and death can pass over us. It’s always been true. The blood enabled death to pass over the Israelites, the death we are owed for our sin. God does it because it’s His delight. He delights in steadfast love, in mercy.
