Can I live without it?
As much as it can feel like it at the time, giving up that thing you feel you can’t isn’t a matter of life or death.
Your life is made full not through the things you have or do but through Christ.
If you can’t answer yes to the question above, then you need to go back to questions one and two and really be completely honest with yourself.
In addition to this, praying and reminding yourself that God will provide for you by studying His word and reflecting on His many blessings can bring you to a place where you’re ready to give up what He asks.
