The writer of Hebrews said of Jesus,
“who, in the days of His flesh, when He had offered up prayers and supplications, with vehement cries and tears to Him who was able to save Him from death, and was heard because of His godly fear” (Hebrews 5:7).
Jesus did not hesitate to become emotional in His prayers, especially as He cried out for deliverance from death, and because of His godly fear, the Father heard Jesus, and He escaped the long torturous ordeal of the cross, suffering for only six hours rather than three to five days, as often happened.
Do you want God to hear your prayers? Pour out your emotions to Him. Whoever convinced us that we should not show emotions in our religion, did not know what he was saying, and did not know the Scriptures.
However, the pouring out of emotion before God means nothing to Him, if we do not live in godly fear, as Jesus did.
