The Lord Jesus teaches the Jews that were following Him:
Matthew 7:22-23 Many will say to Me on that day, ‘Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness.’
Matthew 21:22 And all things you ask in prayer, believing, you will receive.”
Mark 11:24 Therefore I say to you, all things for which you pray and ask, believe that you have received them, and they will be granted you.
John 14:13-14 Whatever you ask in My name, that will I do, so that the Father may be glorified in the Son. If you ask Me anything in My name, I will do it.
John 15:7 If you abide in Me, and My words abide in you, ask whatever you wish, and it will be done for you.
John 15:16 You did not choose Me but I chose you, and appointed you that you would go and bear fruit, and that your fruit would remain, so that whatever you ask of the Father in My name He may give to you.
John 16:23-24 In that day you will not question Me about anything. Truly, truly, I say to you, if you ask the Father for anything in My name, He will give it to you. Until now you have asked for nothing in My name; ask and you will receive, so that your joy may be made full.
John 16:26 At that day ye shall ask in my name: and I say not unto you, that I will pray the Father for you:
John reminds the Jews:

1 John 5:14 This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us.

Acts 4:12 And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved.”
Paul writes to Believers:
Romans 8:32 He who did not spare His own Son, but delivered Him over for us all, how will He not also with Him freely give us all things?
Colossians 3:17 Whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks through Him to God the Father.
1 Corinthians 1:2 To the church of God which is at Corinth, to those who have been sanctified in Christ Jesus, saints by calling, with all who in every place call on the name of our Lord Jesus Christ, their Lord and ours:
1 Corinthians 15:1-4 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:
Romans 10:9-13 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. For the scripture saith, Whosoever believeth on him shall not be ashamed. For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
For whosoever shall call upon the name of the Lord shall be saved.
