Jesus Christ's work, as revealed through His life and ministry, centers on His profound relationship with His Father and the mission He was sent to fulfill. From a young age, as seen in Luke 2:49, He was acutely aware that He was not Joseph's natural son but the Son of God in heaven, understanding that His Father had a purpose and a work that He was eager and willing to undertake. Even at twelve years old, He was already engaging with teachers in the temple, demonstrating His readiness to be about His Father's business. A significant aspect of His mission was to reveal the existence of His Father in heaven, a task vital to answering who governed the universe while He was on earth as a limited human. This revelation was necessary to declare the Father's sovereignty and power. Throughout His ministry, Jesus emphasized His intimate connection with the Father, stating in John 14:9 that whoever has seen Him has seen the Father, reflecting Their profound likeness and unity. He affirmed in John 8:26-29 that He spoke only what the Father taught Him, and that the Father was always with Him, never leaving Him alone as He did what pleased Him. Jesus' words and works were fully authorized and guided by the Father, as He reiterated in John 10:38, urging belief in this unity so that others might understand the Father's presence in His ministry. Every action and teaching reflected the Father, providing insight into His character and nature. In John 1:18, it is declared that no one has seen God at any time, but Jesus, being in the bosom of the Father, has expounded Him, offering a detailed explanation through His teachings and actions, not merely an introduction. This declaration of the Father is crucial to salvation, as Jesus stated in John 17:3 that eternal life is to know the only true God and Jesus Christ whom He sent. His role as a light in John 12:45-46 implies a deeper contemplation, using the Greek term theoron, which suggests not just seeing but understanding and participating in the divine through serious meditation on His words and worship. This process leads to belief, repentance, and living in the light, ultimately fostering intimate fellowship with the Father and the Son, mirroring the relationship They share. Finally, in I John 1:1-3, the purpose of Jesus' declaration is reiterated, aiming to bring believers into fellowship with the Father and the Son, and with each other, highlighting the ultimate goal of developing this intimate connection through beholding and learning from the Son.

Jesus Christ fulfilled the roles of both sacrificial animals in the Day of Atonement ritual. He died to provide a covering of blood, opening the way to the Father, and He also bore the sins of many, taking them to the land of forgetfulness, the grave. The expiation of mankind's sins—the atoning, cleansing, disannulling, purging, and putting away of sins—is what the Savior accomplishes, as defined by the very essence of the holy day. In Colossians 2, Paul emphasizes that believers are already complete in Him, with their sins fully taken care of under Christ's blood, not awaiting any future resolution involving another being. Hebrews 1:3 declares that Jesus, by Himself, purged our sins and sat down at the right hand of the Majesty on high, signifying the completion of His work regarding sin. Hebrews 9 and 10 further elaborate on Christ's fulfillment of the cleansing ritual, entering the Most Holy Place in heaven with His own blood, mediating the promise of eternal inheritance without any dependence on another entity. His sacrifice alone put away sin, canceling it and bringing it to nothing for those who repent and come under His blood. Hebrews 10:1-4 and 10:10-14 affirm the completeness of Christ's sacrifice, sanctifying believers once for all, with no further offering for sin needed, as their sins are no longer remembered under the New Covenant. His role as the author and finisher of our faith encompasses the full resolution of human sin, bearing it to a land of forgetfulness, as typified in the ritual of kippur and kaphar.

The intercessory work of Jesus Christ stands as a profound example of selfless dedication to the will of God. As the perpetual High Priest, He extends aid to those who approach God through Him, sympathizing with our weaknesses, having been tempted in all points as we are, yet without sin. Through His intercession, the prayers and praises of believers become acceptable to God, allowing us to come boldly to the throne of grace to obtain mercy and find help in time of need. Jesus Christ, as the ultimate Intercessor, bore the iniquities of many, making intercession for transgressors. Despised and rejected, He was wounded for our transgressions and bruised for our iniquities, carrying our griefs and sorrows. By His stripes, we are healed, as the Lord laid on Him the iniquity of us all. His sacrifice, offered once for all, perfected forever those who are being sanctified, securing eternal redemption through His blood as He entered the Most Holy Place in heaven itself to appear in the presence of God for us. As our Advocate with the Father, Jesus Christ the righteous is the propitiation for our sins and for the whole world. He continually intercedes, living always to make intercession for those who come to God through Him, saving to the uttermost. His intercessory ministry, based on the finality of His sufferings, ensures that even when vindicated by God, He remains concerned to minister to His people. He pleads for and obtains the fulfillment of the promises of the everlasting covenant, securing grace and strength for us against our adversaries. Jesus sets a powerful example by commanding intercession even for enemies, urging us to love them, bless those who curse us, and pray for those who spitefully use us, reflecting the perfection of our Father in heaven. He promises answers to prayers made in His name, encouraging us to ask, seek, and knock with the assurance that our requests will be granted. His intercessory prayers, especially as recorded in John 17, reveal His deep concern for the unity and protection of His followers, praying not only for His disciples but for all who would believe in Him through their word, that they may be one as He and the Father are one. Through His work, Jesus Christ inspires the church to engage in intercessory prayer as a royal priesthood, bearing the loving burden of others. His example and sacrifice enable believers to participate in the effective bearing of others' burdens, imitating His High Priestly role within our earthly lives. His ongoing intercession in heaven, presenting the merits of His death, guarantees our salvation, ensuring that all things work together for good as God the Father answers the pleas of His Son on our behalf.
