I find the following excerpt taken from the Bible in One Year with Nicky Gumbel quite interesting and practical. Hope you think so also.
Intercession for deliverance (from your problems)
Sometimes in our own lives we are faced with seemingly insurmountable problems. This is a great model of how to deal with them. Hezekiah did not despair. He did not panic. He did not give up. He turned to God in prayer.
This account of Hezekiah’s prayer and God’s deliverance is recorded three times in the Old Testament – see also Isaiah 36–39 and 2 Chronicles 32. The events of this period are corroborated by Babylonian sources.
When Hezekiah received the threatening letter and was faced with a seemingly insurmountable problem, ‘He went up to the temple of the Lord and spread it out before the Lord’ (19:14). He prayed to the Lord, ‘O Lord … you alone are God over all the kingdoms of the earth. You have made heaven and earth. Give ear, O Lord, and hear; open your eyes, O Lord, and see … Now, O Lord our God, deliver us from his hand, so that all kingdoms on earth may know that you alone, O Lord, are God’ (vv.15–19).
Hezekiah’s intercession begins by consciously recognising who God is. As Andrew Murray says, ‘The power of prayer depends almost entirely upon our apprehension of who it is with whom we speak.’ When we intercede we are speaking to the one who alone is, ‘God over all the kingdoms of the earth’ (v.15). He has the power to resolve these seemingly insurmountable problems.
Hezekiah’s prayer was for God’s honour and glory, ‘so that all kingdoms on earth may know that you alone, O Lord, are God’ (v.19). Jesus taught us to start our prayers, ‘Hallowed be your name, your kingdom come’ (Matthew 6:9–10)
I love the expression, ‘He … spread it out before the Lord’ (2 Kings 19:14). He spoke to God about the problem. The apostle Paul writes, ‘Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus’ (Philippians 4:6–7).
The prophet Isaiah sent a message to Hezekiah saying that God had heard his prayer. He delivered the people from the threat of the Assyrians in answer to Hezekiah’s intercession.
Hezekiah also prayed for his healing. He was ill, at the point of death (2 Kings 20:1), and he interceded on his own behalf: ‘Hezekiah turned his face to the wall and prayed to the Lord’ (v.2). Again, God answered his intercession: ‘I have heard your prayer and seen your tears; I will heal you … I will add fifteen years to your life’ (vv.5–6).
Hezekiah experienced God’s amazing blessings in answer to his intercession. However, the passage ends with a note of warning. When envoys came from Babylon, Hezekiah showed off all his treasures (vv.12–15). He appeared to be taking the glory for all that the Lord had given him. Isaiah told him that as a result, ‘nothing will be left’ (v.17). If we take the glory for what the Lord does for us, it is at our own peril.
