Luke 22:41-44
And He withdrew about a stone’s throw beyond them, where He knelt down and prayed, “Father, if You are willing, take this cup from Me. Yet not My will, but Yours be done.” Then an angel from heaven appeared to Him and strengthened Him. And in His anguish, He prayed more earnestly, and His sweat became like drops of blood falling to the ground.

During the days of Jesus’ earthly life, He offered up prayers and petitions with loud cries and tears to the One who could save Him from death, and He was heard because of His reverence.

Philippians 4:6
Be anxious for nothing, but in everything, by prayer and petition, with thanksgiving, present your requests to God.
Psalms 77:2
In the day of trouble I sought the Lord; through the night my outstretched hands did not grow weary; my soul refused to be comforted.
James 5:13-18
Is any one of you suffering? He should pray. Is anyone cheerful? He should sing praises. Is any one of you sick? He should call the elders of the church to pray over him and anoint him with oil in the name of the Lord. And the prayer offered in faith will restore the one who is sick. The Lord will raise him up. If he has sinned, he will be forgiven. Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man has great power to prevail. Elijah was a man just like us. He prayed earnestly that it would not rain, and it did not rain on the land for three and a half years. Again he prayed, and the heavens gave rain, and the earth yielded its crops.
Hebrews 4:14-16
Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold firmly to what we profess. For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who was tempted in every way that we are, yet was without sin. Let us then approach the throne of grace with confidence, so that we may receive mercy and find grace to help us in our time of need.
Psalms 88:1
O LORD, the God of my salvation, day and night I cry out before You.
Psalms 102:1-2

Ask, and it will be given to you; seek, and you will find; knock, and the door will be opened to you.
Psalms 18:6
In my distress I called upon the LORD; I cried to my God for help. From His temple He heard my voice, and my cry for His help reached His ears.
Psalms 116:1-4
I love the LORD, for He has heard my voice—my appeal for mercy. Because He has inclined His ear to me, I will call on Him as long as I live. The ropes of death entangled me; the anguish of Sheol overcame me; I was confronted by trouble and sorrow. Then I called on the name of the LORD: “O LORD, deliver my soul!”
