I recently surveyed the Gospels to make a list, from the mouth of Jesus, as to how you get into Heaven. What is it that gets you there? Jesus gave many answers, but a cluster of them rose to the top via repetition:
- If you want to be part of the kingdom of God, you must repent and believe. Sin is presented as the antithesis of Jesus and it must be repented from.
- That Jesus Himself is the access point, and Jesus is calling sinners to himself
- That one must be born of the Spirit
- He is looking for faith.
- Obey the Law and keep the commandments (here's where the two commands are applicable).
- Do God's will
- Put the words of Jesus into practice
- Align yourself with Jesus, identify with him, and follow Him
- Love God
- Love Jesus
- Lose your life (deny self) for Jesus's sake
- good works ("love of neighbor")
- Humility
- Live by the truth; come into the light, both of which are Jesus Himself
- Drink the "living water" that Jesus gives
I would say the summary statement is: Repent of your sins and align yourself with Jesus. Come to Jesus, believe in Jesus and follow him—put his words into practice, love him, allegiance. Follow him, identify with him, and learn from him.
> And what keeps them saved
The Spirit of God keeps you saved as you hold the course.
> how do they absolutely know they are saved?
It's a promise from God. If you do what Jesus asks for salvation, you can absolutely know you are saved. You will also be aware of the Holy Spirit within you, and that's an indicator also.
