The New Birth
Being born again, or regeneration, is the same as being taken from darkness to light. Without new birth we will remain in our sinful nature and will not enter the kingdom of God.
Hebrews 9:22 - The Blood of Jesus Christ
In the Old Testament God showed that redemption can only be attained through blood (Hebrews 9:22). This pointed to the blood of Christ as the only sufficient means to cleanse man's guilt and clear his conscience.
