Luke 2:36-37 Now there was one, Anna, a prophetess, the daughter of Phanuel, of the tribe of Asher. She was of a great age, and had lived with a husband seven years from her virginity; and this woman was a widow of about eighty-four years, who did not depart from the temple, but served God with fastings and prayers night and day.
Matthew 26:40-41 Then He came to the disciples and found them sleeping, and said to Peter, “What! Could you not watch with Me one hour? Watch and pray, lest you enter into temptation. The spirit indeed is willing, but the flesh is weak.”
A gap in prayer life is enough for the devil to do great damage.
One thing that leads to unanswered prayers is praying amiss. Romans 8:26-27 In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God.
If what we are praying for is inspired by the Holy Spirit, there must be an answer. When our prayer is in line with God’s will, there is already provision.
James 4:3 You ask and do not receive, because you ask amiss, that you may spend it on your pleasures.
Not that God can’t answer but are you ready and matured to receive or you’ll use the blessings against others. If I act in obedience to the Holy Spirit, breathing is prayer. There is no better place and time to pray than now, as He speaks.
Psalm 20:1-9 May the LORD answer you in the day of trouble; May the name of the God of Jacob defend you;  May He send you help from the sanctuary, And strengthen you out of Zion;  May He remember all your offerings, And accept your burnt sacrifice. Selah  May He grant you according to your heart’s desire, And fulfill all your purpose.  We will rejoice in your salvation, And in the name of our God we will set up our banners! May the LORD fulfill all your petitions.  Now I know that the LORD saves His anointed; He will answer him from His holy heaven With the saving strength of His right hand.  Some trust in chariots, and some in horses; But we will remember the name of the LORD our God.  They have bowed down and fallen; But we have risen and stand upright.  Save, LORD! May the King answer us when we call.
1 Thessalonians 5:17-18 pray without ceasing, in everything give thanks; for this is the will of God in Christ Jesus for you. Prayer creates a wall around us which makes it impossible for the devil to attack. The devil is waiting for an opportune moment to deal with you. Any gap in prayer is enough.
Jesus warned Peter about the devil’s plan and that he must makes sure he does not find him weak. Luke 22:31-32 And the Lord said, “Simon, Simon! Indeed, Satan has asked for you, that he may sift you as wheat. But I have prayed for you, that your faith should not fail; and when you have returned to Me, strengthen your brethren.”
