What does it mean that Jesus is interceding for us in heaven?

from the old testament

• In the Old Testament, intercession involved a person pleading with God on behalf of others, often to seek mercy, forgiveness, or blessing. Abraham interceded for Sodom, pleading for the Lord to spare the city even if there were as few as ten righteous people in the city (Genesis 18:22-33).
• Moses pleaded for Israel after they sinned with the golden calf (Exodus 32:11-14; 33:12-17).
• As a prophet of God, Samuel prayed for Israel’s protection (1 Samuel 7:5-9, 12:23).

from the new testament

• Hebrews 7:25 says of Jesus, "Consequently, he is able to save to the uttermost those who draw near to God through him, since he always lives to make intercession for them." Jesus is in heaven and stands on our behalf before God the Father, making a way for believers to have access to God.
• Hebrews 7 discusses the Old Testament concept of a priest who interceded before God on behalf of another. Yet unlike a human priest who can only intercede for a limited time, Jesus can intercede before the Father "to the uttermost" (v. 25) a phrase also translated "at all times." The contrast is between a human priest who can intercede temporarily and Jesus, the High Priest, who intercedes forever on behalf of His people.
• The meaning of interceding includes intervening on behalf of believers to provide forgiveness of sins. First John 2:1 points out, "My little children, I am writing these things to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous." Jesus is the Advocate of the Christian, working on behalf of those who are His children in order to provide forgiveness and access to the Father.
• Jesus is the only One who intercedes on our behalf before the Father. First Timothy 2:5 states, "For there is one God, and there is one mediator between God and men, the man Christ Jesus." Acts 4:12 also teaches, "And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved."
• Jesus reigns in heaven at God’s right hand and is also present with us through the Holy Spirit, guiding and empowering us. As our great High Priest , He sympathizes with our weaknesses and intercedes on our behalf, giving us confidence to approach God’s throne for mercy and grace in every need (Hebrews 4:14-16). His heavenly reign and intercession assure us that we are never alone and always supported by His love and power.

implications for today

Jesus and only Jesus can intercede on our behalf. He is perfect God and perfect man, yet without sin (Hebrews 4:15). Jesus also fully understands our human experience and temptations. He was tempted by Satan in the wilderness and yet did not sin (Matthew 4:1-10). He lived a holy life and then paid the price for sin through His death on the cross (John 19:30). As 2 Peter 1:3 promises, "His divine power has granted to us all things that pertain to life and godliness, through the knowledge of him who called us to his own glory and excellence."

Further, Jesus is God's one and only Son. At Jesus’ baptism, God the Father spoke: "You are my beloved Son; with you I am well pleased" (Luke 3:22). John 3:16-17 makes clear that Jesus is God’s Son who died so that those who place their faith in Him have eternal life.

Jesus is presently in heaven, advocating on our behalf against the accusations of Satan. Jesus paid for our sin once and for all on the cross. He took on our sin that we might take on His righteousness (2 Corinthians 5:21). As a result, we are now accepted as blameless before God and can boldly approach His throne.
