i dont believe Exodus is a historical fact. i like the imagery and metaphors.
Freedom from sin freedom from slavery.
Are you saying then that you do not believe in the passover and that of the Israelites were being redeemed from bondage in Egypt. Exodus records God's overwhelming acts of deliverance to show His enemies His sovereignty as in "I AM".
If we don't believe the exodus as a historical fact then we can't believe anything that is written in scripture as being historical. Is Jesus a historical fact or just a legend to you and how can you prove this as fact or fiction? We believe all scripture is inspired by God and is truth as the Holy Spirit reveals all the mysteries to us.
We believe by faith: Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen. Like I said, you can't just pick out the parts you like as we need the whole for understanding.
