Hebrews 4: 14-16 Inasmuch then as we have a great High Priest Who has already ascended and passed through the heavens, Jesus the Son of God, let us hold fast our confession of faith in Him.
For we do not have a High Priest Who is unable to understand and sympathize and have a shared feeling with our weaknesses , but One Who has been tempted in every respect as we are, yet without sinning. and infirmities and liability to the assaults of temptation
Let us then fearlessly and confidently and boldly draw near to the throne of grace (the throne of God's unmerited favor to us sinners), that we may receive mercy for our failures and find grace to help in good time for every need appropriate help and well-timed help, coming just when we need it.
(John 16:23-27) And when that time comes, you will ask nothing of Me you will need to ask Me no questions. I assure you, most solemnly I tell you, that My Father will grant you whatever you ask in My Name as presenting all that I AM.
24 Up to this time you have not asked a single thing in My Name as presenting all that I AM; but now ask and keep on asking and you will receive, so that your joy (gladness, delight) may be full and complete.
25 I have told you these things in parables (veiled language, allegories, dark sayings); the hour is now coming when I shall no longer speak to you in figures of speech, but I shall tell you about the Father in plain words and openly (without reserve).
26 At that time you will ask (pray) in My Name; and I am not saying that I will ask the Father on your behalf for it will be unnecessary.
27 For the Father Himself tenderly loves you because you have loved Me and have believed that I came out from the Father.
Undoubtedly it means this much at least, that we are to pray to the Father as revealed in Jesus Christ.
"Whatever you ask the Father in my name" might be translated, "Whatever you shall ask the Father as represented by me." It expresses Christ's identity with the Father. The Father had been known to them before by many different names: "Elohim," the God of nature; "El Shaddai," the God of power; "Adonai," the God of providence; "Jehovah," the God of covenant grace, but henceforth, He is to be known as "Jehovah-Jesus," God in Christ. This is undoubtedly implied in the language of this passage, and involved in the thought to which the Saviour is giving expression. It is the same thought that He repeats in the parallel verse, "Whatsoever you shall ask in my name, that will I do, that the Father may be glorified in the Son." There it plainly expresses that the Father and Son are acting in perfect concert, and it is through the Son only that the Father is glorified and revealed to man or understood by him.
