Acts 14
Now it happened in Iconium that they went together to the synagogue of the Jews, and so spoke that a great multitude both of the Jews and of the Greeks believed. 2 But the unbelieving Jews stirred up the Gentiles and [a]poisoned their [b]minds against the brethren.
3 Therefore they stayed there a long time, speaking boldly in the Lord, who was bearing witness to the word of His grace, granting signs and wonders to be done by their hands.

Two things that stand out in this scripture:
1. The non believing Jews poisoning the minds of those trying to believe will be judged very harshly.

2. The Lord will give us signs and wonders to reveal His truth. We must learn to tap into this authority/faith/power.

If we spend more time in His presence, signs and wonders will follow. This will be done as a witness to our Lord Jesus.
