Can anyone help with Hebrews 10 26-29?

This Scripture pertains to apostasy ( which is a noun which means the abandonment of a religious belief) in other words God's Grace isn't an excuse to sin! However one sin doesn't remove you from the family of God. Willful Sinning day to day to day turns into turning away from God. Or it means this person has never received the fullness of Gods love and Salvation with grace. Because in grace of Jesus is freedom from sin.
