Do We Need A Human Mediator? Bible Question.
“Does a time ever come in the life of a Christian that he sins to the point that, even though he repents, he cannot pray for himself, but must have some righteous brother to pray for him?”
The answer to your question is given clearly by the Word of God itself . . .
“This is good and acceptable in the sight of God our Savior, who desires all men to be saved and to come to the knowledge of the truth. For there is one God, and one mediator also between God and men, the man Christ Jesus,” - 1 Timothy 2:3 – 5 (New American Standard Bible)
First, God wants all people to be saved. Second, there is one mediator between God and us – Jesus Christ. That just does not leave room for any other person to be a mediator between any Christian and God.
The Scripture show that the church of the Lord is “the household of God” (1 Timothy 3:15). Then the apostle Peter writes, “Therefore, putting aside all malice and all deceit and hypocrisy and envy and all slander, like newborn babies, long for the pure milk of the word, so that by it you may grow in respect to salvation, if you have tasted the kindness of the Lord. And coming to Him as to a living stone which has been rejected by men, but is choice and precious in the sight of God, you also, as living stones, are being built up as a spiritual house for a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ.“ (1 Peter 2:1 – 5)
Notice that we – Christians – are a holy priesthood. Christ is our High Priest (Hebrews 4:15, etc.). But each of us is a priest of God, and as such, we have access to God without the intervention of any other human being.
It is right and proper to ask others to pray for us (1 Thessalonians 5:25; 2 Thessalonians 3:1; Hebrews 13:18; etc.). Quite often one feels the need to confess his sins and weaknesses to other brothers (James 5:16), and even to the church, so that they can pray for him. But when one repents, he can ask God to forgive him right then.
Our forgiveness is not based on someone else praying for us, for that would make that person a mediator through whom we must go to have access to God. Christ is the only mediator. That means your brother in Christ, the preacher, the elders, nor even the congregation can serve as a mediator. Your forgiveness is between you and God, with Christ as the advocate or intermediary.
