For those of who have difficulty letting go of things on the grounds that you might need them someday, try trusting the providence of God. God sees you and knows what you need. Let go and trust that if the time ever comes that you need it again, God will provide you with what you need, whether with the funds to buy it, or with friends who let you borrow it.
As you let those things go, pray. Tell God all about it. Tell Him that you trust Him to provide for you. He won’t let you down.
