Your heart to stand as a watchman is precious to the Lord, and it is right to ask Him to strengthen you in that calling. God has given this assignment, and He will give the grace to walk in it with faithfulness.
Hope is what keeps a person going when the night is long and the answer is not yet seen. Without God there is no real hope, but when you have Him, hope is extended and enlarged. Scripture shows that we have been born again to a living hope because Jesus Christ rose from the dead. That resurrection is the foundation of everything we believe. Without it there would be no faith at all, but because He lives, our hope is alive. It is also the hope of an inheritance that is incorruptible and undefiled and does not fade away, reserved in heaven for you, and the hope of eternal life which God, who cannot lie, has promised to those who trust in His Son.
The Lord is called the God of hope, and Paul prayed that He would fill His people with all joy and peace in believing, so that they would abound in hope through the power of the Holy Spirit. One of the ways He does this is through His Word. Through the patience and comfort of the Scriptures we find hope. When you remember what God has spoken, you find comfort and strength not to give up in times of trouble. The one who has this living and blessed hope within him is also moved to purify himself and to live soberly, righteously and godly in this present world as he looks for the Lord.
Hope by its nature is for what we do not yet see. What is already seen is no longer hope. Therefore if we hope for what we do not see, we wait for it with patience. That is true for the watchman as well. You pray for others for change, deliverance, inner healing and victory, and you wait with patience for God to work. You are also waiting for your own breakthroughs where hope has felt deferred. God understands that waiting, and He is patient and faithful. He has subjected us to hope on purpose, so that we would seek Him and trust His promise of eternal glory.
This calling also requires discipline. Scripture says that the one who plows should plow in hope and the one who threshes in hope should share in the hope of a harvest. Your labor in prayer is not without expectation. You can expect a harvest. An athlete disciplines his body, denying himself many things, for a crown that will soon fade. How much more should we discipline ourselves for an incorruptible crown. Paul said he kept his body under control and brought it into subjection, so that after preaching to others he himself would not be disqualified. That same grace is needed to pray when it is not convenient, to rise when you are prompted during the night hours, and to watch and pray without ceasing as you go through the day and evening. God will supply that discipline and grace as you ask Him.
I pray that the Lord will give you clear strategy in prayer for others, that you would know how to pray and what to pray when you do not know what to pray as you ought, and that the Spirit would help you in your weakness. I pray He will grant you sharper wisdom and discernment, and treasures of knowledge and understanding from His Word to help others in need. I pray He will help you to live righteously before Him, and to keep a strong desire to intercede even when it costs you comfort or sleep. I pray He will restore and confirm your sense of purpose, reminding you of the hope of your calling in Christ.
And where there has been delay and hope deferred in your own life while you have faithfully prayed for others, I pray the Lord will bring acceleration and release in those very areas where you need breakthrough most. May the God of hope fill you with joy and peace as you trust Him, and may you abound in hope, encouraged and strengthened to continue this work until you see His healing power and victories come in Jesus name.
