Jesus showed Himself trustworthy by gaining the victory over sin when we were the transgressors. Through His resurrection, justifying work, and exaltation, Christ is worthy of our trust and confidence. When the apostle Peter read Isaiah 53 and saw what Jesus had done for His people, his response was to see Jesus’ suffering as a model of His faithfulness, so that no matter what we are experiencing or facing, we can trust ourselves to Him.
Trusting others presents massive challenges in our fallen world. Everyone has been corrupted by sin, and therefore fails to be fully faithful or trustworthy. As says, “Many a man proclaims his own loyalty, but who can find a trustworthy man?”
While humans prove to be both distrustful and untrustworthy, God presents Himself as the One we can supremely trust for everything in this life and beyond the grave. We see an intentional emphasis in Scripture on the trustworthiness of God, but Scripture does not command us to have a blind faith. The Lord instructs us to trust Him, and then He demonstrates He is worthy of our trust. God never speaks, then fails to act. He always proves Himself faithful.
Despite this truth, we often struggle to trust God, which manifests itself when we give in to sin in times of various trials and temptations. So how do we grow our trust of our Lord and His power over our sin?
We find a helpful answer to this question in Isaiah 53. Here, God reveals His Suffering Servant, the Lord Jesus as eminently trustworthy. Whether we suffer because of trials or temptations, Jesus can be trusted to see us through and bring God’s covenant promises to fruition.
There are four ways Isaiah shows Jesus’ trustworthiness in this passage.
First, Jesus humbled Himself when we were proud.
At the start of this chapter, Isaiah laments Israel’s unbelief. Just before, in Isaiah 52, we learn that the Gentiles would marvel at the exalted Servant. Yet when the scene flips to Isaiah 53, regardless of the magnificent salvific promises of the previous passage, we observe the ongoing disbelief of people who have had a front-row seat to God’s work. What makes God’s promises so difficult to trust? Isaiah answers by showing us the Servant’s humility alongside the pride of sinners who reject God’s word.
Isaiah gives a description of the Servant’s humility, using agricultural pictures to convey Jesus’ outward appearance as useless and unfruitful. The Servant came in the humblest of ways, and His circumstances and appearance made Him look dispensable. Peoplewould have contempt for God’s Messiah and suffering Servant.
Thus, we see both the humiliation of the Servant and the pride of man. God in human flesh descends to us, and we despise Him because He does not meet our ideals. God, however, sees us in our pride, knows how we will respond, and still comes to save us from sin.
Jesus proves Himself trustworthy in His willing humiliation for prideful sinners. Isaiah includes himself in those who thought little of the Servant, saying, “We did not esteem Him.” We must include ourselves in that we. Apart from God’s grace, we rejected Him. Christ, though, condescended to save us, showing He is trustworthy.
Second, Jesus was faithful when we were not.
Isaiah paints a rather ugly picture of us.
