21 In answer Jesus said to them: “Truly I say to you, if you have faith and do not doubt, not only will you do what I did to the fig tree, but even if you say to this mountain, ‘Be lifted up and thrown into the sea,’ it will happen.+

8 But you will receive power when the holy spirit comes upon you,+ and you will be witnesses+ of me in Jerusalem,+ in all Ju·deʹa and Sa·marʹi·a,+ and to the most distant part of the earth.”+

41 So those who gladly accepted his word were baptized,+ and on that day about 3,000 people were added.+
