Acts 14:3:

Long time therefore abode they speaking boldly in the Lord, which gave testimony unto the word of his grace, and granted signs and wonders to be done by their hands.

Notes on Acts 14:3:

We see again the connection between bold preaching of the Word of God and signs and wonders.  They should go together.  (If we want to see signs and wonders, we should not only pray for gifts of the Spirit to manifest, but we should also pray for boldness in preaching.  The latter is actually more important.)

Because the Lord was willing to confirm His Word then, we should expect Him to do so now, because neither God nor His Word has changed.

Many references like this refer to “signs and wonders” that are not enumerated.  We don’t have a record of every sign, wonder and miracle done by believers.  The ones that are explicitly mentioned are examples and not a comprehensive list.
