Your request for protection and wisdom with your finances is a small part of a far greater battle. Why tremble at the thought of a hacker when the devil himself prowls like a roaring lion, seeking whom he may devour? Do not mistake the real threat. The enemy attacks most fiercely when we are isolated, relying on our own cleverness. But the sheep that stay within the fold of the Good Shepherd, banded together in faith, hear His voice and are secure. No one can snatch them out of His hand. Is your first anxiety the safety of your bank account, or the safety of your soul?
Do what prudence demands: secure your accounts, cancel what is weak. But do not think that worldly wisdom alone is your shield. The wisdom of this world, which trusts in firewalls and passwords, comes to nothing. The true wisdom is from above, hidden from the rulers of this age, but given to the perfect in Christ. If you are in Christ, you have access to a security that moth, rust, thieves, and hackers cannot touch. Where is your treasure? If it is stored in heaven, what hacker can break in? If your heart is set on earthly support, you will mourn every loss like a heathen who has no hope. But if your hope is in the risen Lord, you can say, "The Lord gave, and the Lord has taken away; blessed be the name of the Lord."
You cry out for protection on your finances, for wisdom in spending, investing, saving, and giving. A good prayer, but do not let the cares of life strangle it. Seek first the Kingdom of God and His righteousness, and all these things, yes, even a roof and bread, will be added to you. Are you anxious? Hear the Lord Himself: "Come to me, all you who labor and are heavy laden, and I will give you rest." Not rest only from hackers, but rest from the crushing weight of anxiety about tomorrow. He does not promise to make you rich; He promises to place you in all security, in Himself.
True freedom is not a robust portfolio. True freedom is virtue, a conscience at peace, and the fear of God that makes you fear nothing else. Flee from the devil’s snare of greed and grasping. Run as one who has seized the prize: chastity, honesty, contentment, generosity. If you flee far enough, the enemy will cease to pursue. So spend as a steward, not an owner. Invest in the bellies of the poor, which yield an eternal return. Save, but store up a good foundation for the time to come. Give, and it will be given to you, pressed down, shaken together, running over. This is the wisdom of the perfect: to use the fleeting mammon to secure eternal dwellings.
Do all your due diligence with a clear head, but cast every final care upon Him who cares for you. Do not face these threats alone, but seek the counsel of the faithful, and let the church surround you. The One who came out of the temple to give Himself up for your sins knows your every need. He who went into the wilderness to be tempted for you will strengthen you against every assault. So be diligent, but stand firm in faith, and the peace of God which surpasses all understanding will guard your heart and your mind in Christ Jesus.
