C. The Bible claims that miracles prove Bible writers (& other Prophets) were inspired by God.
Bible writers and prophets said that miracles done through them confirmed that their message was from God.
a. Old Testament prophets.
-Exodus 4:1-9 - Moses feared that the people would not believe God had sent him. So God gave him signs expressly to convince the people to believe.
-Exodus 14:30, 31 - After the crossing of the Red Sea, the people believed the Lord and His servant Moses.
-Joshua 3:7-17 - When Joshua led Israel across the Jordan on dry ground, God said this showed the people that He was with Joshua as He had been with Moses.
b. New Testament prophets.
-Mark 16:20 - Jesus sent apostles to preach, and as they did so, He worked with them, confirming the word by the signs He gave them.
-Acts 14:3 - God spoke through Paul and Barnabas. He bore witness to the word of His grace, granting signs and wonders to be done by their hands.
-2 Corinthians 12:11, 12 - Signs, wonders, and miracles would confirm one was an apostle.
-Hebrews 2:3, 4 - God bore witness to the message of salvation by signs, wonders, etc.
People needed a way to distinguish true prophets from false ones. If men could do works that could be performed only by the power of God, people would know God was working in those men and they would believe the message preached. Miracles were a deliberate demonstration by God to prove that He exists, that Jesus is His Son, and that the Bible writers and prophets were His spokesmen.
D. Biblical miracles show expressions of God's character and love.
A valuable way of understanding the meaning of miracles is to examine the various terms for miracles used in the Bible. Both the OT and the NT use the word sign (Is. 7:11, 14; John 2:11) to denote a miracle that points to a deeper revelation. Wonder (Joel 2:30; Mark 13:22) emphasizes the effect of the miracle, causing awe and even terror. A work (Matt. 11:2) points to the presence of God in history, acting for mankind. The NT uses the word power (Mark 6:7) to emphasize God's acting in strength. These terms often overlap in meaning (Acts 2:43). These terms are also more specific than the more general term "miracle." As with the OT, the NT miracles are essentially expressions of God's salvation and glory.
Why did Jesus perform miracles? Jesus answered this question Himself: "The blind receive sight, the lame walk, those who have leprosy are cured, the deaf hear, the dead are raised, and the good news is preached to the poor" (Matt. 11:5). With these words, Jesus declared that His miracles were the fulfillment of the promises of the Messiah's kingdom as foretold by Isaiah (24:18-19; 35:5-6; 61:1). Jesus' miracles were signs of the presence of the kingdom of God (Matt. 12:39).
This theme of the miracles pointing to the kingdom of God was developed and deepened especially in the Gospel of John. John presented the miracles of Jesus as "signs" on seven occasions. He thought of these miracles as pointing to deep spiritual truth, demanding obedient faith (John 2:11, 23-25).
Jesus also understood His miracles as evidences of the presence of the kingdom in His ministry (Matt 11:2-5; 12:28). Every miracle story was a sign that God's salvation was present. But not only did the kingdom come; it came in great power, because the dead were raised (Is. 26:19; Luke 7:11-15) and Satan was bound (Mark 3:27). Jesus' miracles were also performed upon the most unlikely people. Jesus consciously brought the salvation of God to those who were rejected. He healed the lame (Matt. 9:1-8), the dumb (Matt 9:32-33), and lepers (Luke 17:11-19). Jesus brought the kingdom to all, regardless of their condition. But Jesus' miracles were not theatrical sensations. He demanded faith of others (Matt 9:2). The hemorrhaging woman was healed because of her faith (Matt 9:18-26). Finally, we gain a deeper understanding of Jesus in His miracles. He is the Lord over nature (Mark 4:35-41) and death (Luke 8:41-46; John 11:1-44). He is the Suffering Servant who bears the infirmities of others (Matt 8:16-17). He is the Messiah who was to come (Matt 11:2-6). He fights the battle against evil (Mark 3:23-30; Luke 11:18-23).
