Jesus replied, “Have faith in God [constantly]. I assure you and most solemnly say to you, whoever says to this mountain, ‘Be lifted up and thrown into the sea!’ and does not doubt in his heart [in God’s unlimited power], but believes that what he says is going to take place, it will be done for him [in accordance with God’s will]. [Matt 17:20; Luke 17:6; 1 John 5:14] For this reason I am telling you, whatever things you ask for in prayer [in accordance with God’s will], believe [with confident trust] that you have received them, and they will be given to you. Whenever you stand praying, if you have anything against anyone, forgive him [drop the issue, let it go], so that your Father who is in heaven will also forgive you your transgressions and wrongdoings [against Him and others]. [But if you do not forgive, neither will your Father in heaven forgive your transgressions.”]
They came again to Jerusalem. And as Jesus was walking in the [courts and porches of the] temple, the chief priests, the scribes, and the elders came to Him, [Matt 21:23-27; Luke 20:1-8] and began saying to Him, “By what authority are You doing these things, or who gave You this authority to do these things?” Jesus said to them, “I will ask you one question, and you answer Me, and then I will tell you by what authority I do these things. Was the baptism of John [the Baptist] from heaven [that is, ordained by God] or from men? Answer Me.” They began discussing it with each other, saying, “If we say, ‘From heaven,’ He will say, ‘Then why did you not believe him?’ But shall we say, ‘From men?’ ” —they were afraid [to answer because] of the crowd, for everyone considered John to have been a real prophet. So they replied to Jesus, “We do not know.” And Jesus said to them, “Neither will I tell you by what authority I do these things.”
