Leviticus 17:11

       “For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that makes atonement for the soul.” We know that the life is in the blood as seen when God asked Cain where his brother was and then said to Cain “The voice of your brother’s blood cries out to Me from the ground” (Genesis 4:10b). Psalm 49:8 Tells us “For the redemption of their souls is costly”. God gave us the blood upon the altar to make atonement for our souls, and it was very costly. We cannot earn salvation, work for it, pay for it. God did everything, paid everything and covered everything with the precious Blood of His Son. It’s a simple witnessing tool for us to use in leading others to Christ. Tell them what He did without making them feel guilty for what they did. Just tell them God did it all to save them they just need to acknowledge it, receive it and make it their own.
