Luke 16:13 “No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money.”
Jesus warns us about the love of money in many places, both through parables and directly.
It is not money which is evil, but the love of it which is... If we run after money more than we run after God, then we are putting God after our riches...
Why not try give someone in need a boost instead of saving up to buy something you are yearning for?
