Let not your heart be troubled: ye believe in God, believe also in me.
The Jewish people had followed God for centuries. They had His Word, full of His promises and prophecies. They passed down the stories of all of His mighty acts and had, through them, gotten to know Jehovah God. They still prayed to Him and worshiped Him and sought Him for themselves, surely having their own personal experiences with Him. But now Jesus was here, the promised Messiah, the one who would bring salvation to Israel. But Jesus was so much more than a man who did amazing things and would be a deliverer of the nation.
Jesus wanted His disciples to understand who He really was. They understood that He was the Messiah, but He wanted them to know that He was God, as well. As they are about to face a confusing time of loss and sadness, He wants them to know that they don’t have to be afraid. He’s telling them that they can trust Him like they trusted His Father. His promises are also true and sure and will never fade. He wants them to know that He will never let them down and that He will uphold them. He wants them to know that everything He was saying would come to pass, that they had hope, that something good would come if they just had faith. He wanted them to know for sure that He was as steadfast as His Father.
The thing that the Pharisees hated most about Jesus were His claims that He was God. But that should have been reassuring to the disciples and should be to us, as well. Jesus was as powerful and able as the God they already trusted in, the faithful one they looked to for answers and guidance, the one who had given the law and shown Himself mighty. They could have the same reliance on Jesus that they had on God the Father, and we can, too.
So if we believe in God the Father, then let us also believe in God the Son. His works and His words come from the same place of truth and love. He had shown Himself just as faithful. He had demonstrated His infinite love. He had shown Himself wise and full of mercy. And He wanted those who knew and loved Him best to understand who He was. Have we accepted these truths about Jesus for ourselves? Do we know Him personally? Do we understand that He is God? Then let our hearts not be troubled. Let us refuse to give in to fear and worry when the God of all creation dwells within our hearts, and let us trust Him fully.
