Don't you need to be in an agreement/ contract with God? Joel Olsteen thinks there might be a back way in. Good people Don't go to heaven, forgiven people do.
Matthew 7:14 *Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.
John 10:1 *¶Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber.
John 10:7 *Then said Jesus unto them again, Verily, verily, I say unto you, I am the door of the sheep.
Not a door. THE door.
As far as I know there was only the law of sin and death where you had to do and live and pay with the blood of animals and the law of grace where you had to believe in Jesus's saving power and live and rely on His blood to save you.
Law always has a place and work distinct and wholly diverse from that of grace. Law is God prohibiting and requiring; grace is God beseeching and bestowing. Law is a ministry of condemnation; grace, of forgiveness. Law curses; grace redeems from that curse. Law kills; grace makes alive. Law shuts every mouth before God; grace opens every mouth to praise Him. Law puts a great and guilty distance between man and God; grace makes guilty man nigh to God. Law says, "An eye for an eye, and a tooth for a tooth"; grace says, "Resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also." Law says, "Hate thine enemy"; grace says, "Love your enemies, bless them that despitefully use you." Law says, do and live; grace says, believe and live. Law never had a missionary; grace is to be preached to every creature. Law utterly condemns the best man; grace freely justifies the worst (Luke 23:43; Rom. 5:8; ! Tim 1:15; 1 Cor. 6:9-11). Law is a system of probation; grace, of favor. Law stones an adulteress; grace says, "Neither do I condemn thee: go, and sin no more." Under law the sheep dies for the shepherd: under grace the Shepherd dies for the sheep.
