Jesus used many lessons to prove God’s willingness to help. He used examples of God’s care in nature (Matthew 6:25-26). He used examples of family love, showing “how much more” the heavenly Father cares (Matthew 7:9-11). He also used the miracles themselves as examples for building faith in God’s power and kindness. He told a healed woman, “Your faith has made you well.” He told a soldier,
“Go; let it be done for you as you have believed.” And the servant was healed at that very moment (Matthew 8:13).
When Jesus did an amazing miracle to a tree, He used it as an example for His apostles. Yet He used words showing that the basic lesson—“have faith in God”—was for all people (“anyone”):
Jesus answered them, “Have faith in God. Truly, I say to you, whoever says to this mountain, ‘Be taken up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will come to pass, it will be done for him. Therefore I tell you, whatever you ask in prayer, believe that you have received it, and it will be yours (Mark 11:22-24).
The miracles were like spiritual windows. People could look into the power of God at work in Christ. Jesus did not heal every sick person in the world, or even all the sick in Israel. Jesus did heal every case of every kind of illness brought to His attention (Matthew 4:23-24; 8:16; 9:35). He never failed. He proved God’s power to help every person who comes to Him. He used the healing of diseased bodies to prove that He could also heal man’s sinful spirit (Luke 5:17-26). He used the healing of the blind to prove that He could give spiritual sight to all who are willing to learn (John 9). He used the feeding of over 5000 to prove that He is “the living bread” for eternal life (John 6). He threw out demons to prove His power to throw Satan out of any person (Luke 11). He raised the dead to prove that He has power to raise up the spiritually dead, as well as those in earthly graves (John 5:25-29; 11:1-45). Jesus did not raise up every dead person in Palestine. He raised up enough to serve as clear examples. These and His other miracles were enough to make His message clear: Place your faith in God and in His Son, Jesus. God has the desire and the power to help each one of us who comes to Him through Christ. Jesus said to His followers,
Do not let your hearts be troubled. Believe in God; Believe also in Me (John 14:1).
