Moving into our third study of the "solas" we come to solus Christus. If justification comes to us by faith alone and from God’s grace alone it cannot be forgotten that it is all through the work of Christ alone. Here we see it all come together through the finished work of Christ on the cross. It is the gospel story, plain and simple.
Adam, being the first man was required to keep the law but he did not and fell into sin. He and all of his descendants came under the curse of God’s wrath (Genesis 2:15-17; Romans 5:12-21). God intervened with a covenant of grace with the people of his choosing. God reckons these as righteous based on the work of Christ who came and lived a perfect, sinless life, died on the cross and rose again in three days and ascended to heaven to sit at the right hand of God. God made him to be sin who knew no sin (Corinthians 5:21). His righteousness is imputed to his children and they are reckoned as sinless. God did not, of course have to provide this covenant and yet he did so because of his great love for his people.
In the closing of his sermon, The Sufficiency of Christ Alone, John MacArthur stated, You come to Christ, you receive the forgiveness of sins. You come to Christ, you receive a new nature, a new disposition, a new heart that loves righteousness. You come to Christ and you die to the past and you rise to new life. You come to Christ and you’re delivered from the kingdom of darkness into the kingdom of His dear Son. You come to Christ and you literally come to the truth that transcends, the truth you’ll never find anywhere except in the Word of God and even this truth you’ll never understand until the Spirit of God takes up residence and becomes your teacher, and then you know the deep things of God. It’s all in Christ. All truth, all wisdom, all knowledge, all understanding, all peace, all joy, all value, all fulfillment, all satisfaction, all purpose, all deliverance, all strength, all comfort, and all eternal hope is in Christ. To have Him is to have everything. Not to have Him is to have nothing. What a powerful proclamation. Read the whole sermon here.
