Christ alone is sufficient for salvation because He fulfills the requirements of God's law and provides righteousness for believers.
The doctrine of 'solus Christus' emphasizes that Christ alone is the source of salvation. According to the Scriptures, God requires perfect righteousness and satisfaction for sin, which only Jesus, through His life and death, can provide. In Galatians 4:6, we learn that God sends His Spirit into our hearts because we are His sons, highlighting our adoption through Christ's work. Furthermore, our assurance of salvation rests on Christ's finished work, not on any efforts of our own. As Paul articulates in Romans 8:1, there is no condemnation for those who are in Christ Jesus. Thus, the Gospel points us to Christ alone, underscoring that all blessings and mercies flow from Him, and we can find complete sufficiency in Him.
