We can know Jesus can heal us through faith based on His power demonstrated in Scripture, such as the miracle healings performed during His ministry.
The ability of Jesus to heal is established through numerous accounts in the Gospels. In Mark 5, the woman with the issue of blood demonstrates her faith by seeking Jesus amidst a crowd, believing that touching His garment would heal her. This narrative, along with others throughout the Gospels, assures believers that Jesus possesses the divine power to heal both physically and spiritually. Furthermore, Jesus is recognized as having the authority to forgive sins, which is the ultimate healing from the spiritual sickness of sin. Thus, knowing that Jesus is the same yesterday, today, and forever (Hebrews 13:8), we can be assured of His ability to heal us in our time of need.
