Both of these, I think, are quite serious sins
Yes. Any sin is.
the most difficult for me. It almost feels impossible.
It is impossible. as Jesus Says, impossible for men, possibe with God. Trust God, not men.
A lot of horrible things have happened to me in my life, and while money hasn't really helped, it has stopped me worrying about it.
Sorry to hear that.
I have real serious issues with anxiety and depression, and the thought of giving away all my money seems just too difficult.
Its like being a chauffeur for someone rich. IF you think the car is yours, and drive off with it, or do not what the owner says, you get arrested or in trouble usually.
Do what the owner (in this case God) Says. Literally sign over the title to Him. Sign over your life and everything in it, thoughts, dreams, hopes, values, imaginations, work, family, possessions,
sign it ALL over to Him, being willing for HIM to do as HE pleases.
As HE says, this is the only way , the first step to being a disciple.
Yet I know in my heart that I need to be willing to give it all away if I'm called to do it.
Everyone is told they must, as in "TODAY , if you hear HIS voice, do not rebel as they did in the wilderness and perished....."
"Sign it over" willingly to HIM. Do not act presumptuously as if that would please HM, but as Corrie ten Boom illustrated , hold as it were everything in the outstretched upturned palm of your hand, easy to receive, easy to give, as GOD DIRECTS.
I need to trust in God, not money to provide for me. But after experiencing all the horrible things he's puts me through it's tough.
Choose today who to serve, God or money or other. As for me and my house, we will always serve the Lord Almighty God, forever, with no thought of looking to the right or to the left - eyes fixed on Him!
