Romans 8:1-3
Two big things we are free from is the power of sin that leads to death and death itself. Jesus became the ultimate once and for all sacrifice. You see, sin had a cost that must be paid because Adam & Eve did what God told them not to. As a righteous and just God, a blood sacrifice would cleanse a person or people from sin once the sacrifice was done. God had Jesus in place at the beginning of it all, but He waited until a set time to send Him.
The law of Moses was/is a guide but has absolutely NO saving power. Jesus took our sin with Him on the cross. Once He went back to Heaven, the Holy Spirit came to earth to help us live. Having Him in our life is SO helpful! Sometimes we just need to learn more about Him. He leads & guides us and it is freeing to let Him!
