How do we know Jesus' sufficiency is true?

The sufficiency of Jesus Christ is demonstrated through His actions and the testimonies recorded in the New Testament. In Mark 5, the healing of the woman with the issue of blood serves as a powerful illustration of His ability to restore and heal. She approached Him with the belief that He could heal her condition, emphasizing that faith originates from hearing about who Christ is. Romans 10:17 states, 'faith comes by hearing, and hearing by the Word of God,' which underscores that knowledge of Christ leads to faith in His sufficiency. The culmination of this sufficiency is found in Christ's sacrificial death and resurrection, providing not only physical healing but also spiritual redemption. Thus, we know Jesus' sufficiency is true because it is supported by Scriptural testimony and the transformative experiences of countless believers throughout history.
