Jesus said in Matthew 5:20 that “Except your righteousness shall exceed the righteousness of the Scribes and Pharisees, ye shall in no case enter into the kingdom of Heaven.” This text is very clear--without a certain kind of righteousness no one would enter into the kingdom of Heaven. If death catches you with sins you have been warned about in God’s word, and you did not get a chance to genuinely confess them, you will not inherit eternal life. God has given you everything you need to succeed--repentance, confession, forgiveness, the word of God, the Holy Spirit, the five-fold ministry, and if you miss Heaven you will have no one to blame but yourself. I believe if nobody else remembers how to get into the kingdom of Heaven, God will remember because it is His kingdom, and He doesn’t suffer with memory loss like we do. If the Apostles forget. God will remember. If the Prophets forget. God will remember. If the Evangelists forget. God will remember.
