You cry out for a financial breakthrough and confess a deep weariness in your fight against sin, even wondering if the hardships you now face are a punishment for refusing to join intimacy with that former request for gain. Listen carefully: God does not reward obedience with punishment. Your faithfulness in that moment, however imperfect, was a gift of His grace, not a cause for present calamity. Yet I hear your exhaustion, and I say to you what the Apostle says: there is no temptation taken you but such as is common to man, but God is faithful, who will not suffer you to be tempted above what you are able, but will with the temptation also make a way of escape, that you may be able to bear it. This trial of your finances and this drawn-out struggle against sin are not signs of God's abandonment, but often His way of keeping you fleeing to Him. As loving parents sometimes allow their little children to be frightened by shadows so they will run back into their mother's arms, so our merciful Lord permits these pressures to bind you fast to Himself.
You say you feel you do not deserve prayer. Yet the very breath you draw is proof of His grace, for in Him we live and move and have our being. If we were worthy, then Christ died in vain. It is precisely in your mess that the grace of God abounds. Remember: the wages of sin is death, but the free gift of God is eternal life through Jesus Christ our Lord. You did not earn this by your victory over sin, nor do you lose it by your falls while you hate the sin and cling to Him. Do not be deceived into thinking your financial distress is payment for past failure. Such thinking would make your works the measure of God's love, but where works are, grace is no more grace. He does not deal with us according to our sins, but according to His mercy.
Now, regarding this sin that has worn you out: you have resisted, and that is noble, but God often permits the thorn to remain, as He did with Paul, not to crush you but to teach you that His strength is made perfect in weakness. When you find no power in yourself, then the power of Christ rests upon you. Do not lose heart in the battle. The very fact that you are fighting shows the Spirit is within you. No one who has given himself over to sin fights this way. You say nothing can break your connection to God; that is true faith, and you must hold it fast. But do not let it make you slothful; rather, let it fill you with the energy to press on, because He who called you is faithful.
As for your financial need: continue in prayer, but know that sometimes He delays the answer to draw you closer, to teach you to trust not in money but in Him who richly provides all things. He is able to make all grace abound toward you, that you, always having all sufficiency in all things, may abound to every good work. Yet often He allows our outward resources to fail so that we may discover the unsearchable riches of Christ. Do not look to this breakthrough as your savior; look to the One who gives it. Whether He gives or withholds, He is working for your eternal good. The way of escape He provides is not always the sudden removal of the trial, but the patience to endure it with joy.
Therefore, I do pray for you, not because you deserve it, but because Christ has made you a child of God. I pray that you would find the refreshment of His presence in this desert, that the temptation would lose its power as you fix your eyes on the glory set before you, and that He would supply every need according to His riches in glory. Remember, the present sufferings are not worthy to be compared with the glory which shall be revealed in us. Labor for a little while, strip yourself with all readiness for this glorious wrestling, and you shall win the perpetual and imperishable crown. May the God of all grace, who has called you to His eternal glory by Christ Jesus, after you have suffered a while, make you perfect, establish, strengthen, settle you. To Him be glory and might forever.
