Thank you for sharing this burden and for your tender care for this man during a difficult health journey. I am praying with you for him and for you, and I want to encourage you with what Scripture shows us about rest, work, and God's grace.
Jesus said to come to Him, all who labor and are heavy laden, and He will give rest, for His yoke is easy and His burden is light. Often when we feel pressed down and groaning under a heavy load, it is not a burden God Himself has laid on us. We take heavy burdens on ourselves, or we let other expectations be placed on us, and we try in our own strength to make everything work. The heaviest burden any of us can carry is trying to live to please ourselves, to manage everything and keep everything together. That will always leave us agitated and weary. To live to please the Father, to do the will of Him who sent us, is light in comparison, because when God calls us to do something He also gives the strength and ability to do it.
God is also at work in you even in this hard testing. He has saved us by His grace through the finished work of Jesus Christ, not by our own efforts, and He drew us to Himself and gave us faith to believe. That same God continues to work in us, shaping us and removing what does not belong, even when that shaping feels painful and we do not understand it. Scripture tells us to count it joy when we go through trials, because God is preparing us for the work He wants to do through us. If we wait patiently, we will see how many things God will work out when we do not push ahead in impatience.
Part of that waiting is also faithful, quiet work. Scripture exhorts that with quietness we should work and provide for our own needs, not as busybodies but diligently doing what our hands find to do and trusting God for provision. Your desire to help while also needing to work is understandable, and God sees both the compassion and the responsibility you carry. He can provide wisdom for finances and for boundaries, and strength for each day of labor.
Above all, rest in the finished work of Jesus. Our standing before God is not on the basis of our goodness or our efforts, but on what Christ has already accomplished for our redemption. When the work was finished, God rested, and we are invited to rest in Christ's finished work by faith.
I am praying for this man you mentioned, for healing and mercy in his illness, for strength to endure work while he waits for his procedure, and for the doctors who will care for him. I am praying for you as well, for physical strength, for wisdom in finances, and for peace that comes from trusting Christ. I am also praying that God will give both of you wisdom to honor Him in your relationship. Scripture teaches that salvation is through Jesus Christ alone, and that marriage is a lifelong covenant between one man and one woman, with sexual intimacy and living together belonging within that covenant. Ask God to lead you both to walk in purity and to seek godly counsel, so that every decision you make reflects His design and brings honor to Him. May He draw you both closer to Jesus, give you rest under His easy yoke, and show you His faithful provision day by day.
