Christ's sufficiency means He completely fulfills all our needs for salvation and righteousness.
To affirm that Christ is sufficient is to recognize that He alone meets all the requirements necessary for our salvation and for a righteous life before God. The sermon emphasizes Christ as our substitute, fulfilling the law perfectly in our stead. Moreover, His sacrificial death and resurrection assure us that His work is complete—'It is finished' (John 19:30). This sufficiency is not just an abstract doctrine but a practical reality for believers who struggle against sin. In 2 Corinthians 12:9, God's declaration that His grace is sufficient further solidifies this concept, as it assures us that our weaknesses are met with His strength through Christ.
