Matthew 24:24. Not all miracles come from God. God is all powerful, but not all miracles come from God. There are people that are not of God that can perform signs and wonders (Matthews 24:24, "For there shall arise false Christs, and false prophets, and shall show great signs and wonders..."). Though the ungodly can have supernatural power, Christians have a stronger power.

Isaiah 11:10. Jesus came on this earth as a standard for all of mankind to follow. He showed us how to love God and to love our neighbor. He is a standard for everyone. If we seek Jesus and put His sinless standard in our heart, we will sin no more and have peace (Isaiah 11:10, "And in that day there shall be a root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek: and his rest shall be glorious").
