17. But, in accordance with his promise, we wait for new heavens and a new earth, where righteousness is at home. 2Pet.3:13
Jesus saves not only us mankind , but also the universe. He saves the spirit, mind and body of us. and he is going to transform our world into the new heaven and new earth.
We Christians do not stop living at our moment of death.
When we became Christians believing Jesus. we started our living with God as travelers unto heaven and as foreigners having citizenship in heaven.
When Jesus comes again, the universe and the world we live on will be destroyed by fire, and the new heaven and new earth will be created again. We Christians will be permitted to enter there to live eternally.
How we may live the lives after death depends on how we lived on this world (Lk16:10-12).Those who built their lives on the word of God believing in Jesus and using their gifts will be committed more big works to their care (Lk16:10-12).
Those who lived wayward lives apart from Christ will be thrown into the eternal fire of judgement (Mt25:24-30;Rev21:8).
18. For I am the Lord who brought you up from the land of Egypt, to be your God; you shall be holy, for I am holy.Lev. 11:45
Holiness is one aspect of God's nature, as He says in here. The holiness of God is the very nature of God, which makes a sharp distinction between Himself and the created world. It stands for His dignity and perfectness as God the maker of the world. And it is simbolized by the fire in the end time of the world, which will judge Satan and the world profaned by it.
For indeed our God is a consuming fire (Hb 12:29).
We, all the people on the earth, are born sinners because of Adam's sin, who was the representative of all mankind. So we by nature can not stand in front of the Holy God. But the God who are not only holy, but also the one of love (1John4:8,9) and forgiveness (Lk15;1John1:9) provided the way for us to be forgiven and sanctified by the Son of God Jesus Christ.
Jesus Christ shed his holy and sinless blood on the cross in behalf of us, so that his holiness and righteousness were given to us as our own ones(1Cor 1:30).
We believers are, therefore, permitted to be present in the face of God wearing the holy cloth of Christ, named "the holy and righteous work of Christ(Gal3:27), and recognized as holy and righteous and sinless ones (2Cor5:21).
On this faith and hope, we Christian strive to walk on the road to holiness by the Scriptures, the Spirit and prayer, in order to become the holy and righteous people of God both in name and reality.
We believers are called the saints, that is the holy ones in Greek. We can not grow as Christians,that is saints, without our putting the word of God into practice, which means daily Bible reading and prayer and following out the teaching of the Bible day by day.
19. I am a good shepherd. The good shepherd lays down his life for the sheep. John 10:11
It says that sheep are so weak animals that they can not find out pasture and water by themselves, can not return to pasture land when they got lost, and can not get up when they fall down to be upside down.
Man should know that he is by nature like these sheep in the face of God. The reason is that he can not find out his spiritual food and water by himself, and can not come home to the Father of his spirit, and does not know the fault living the upside down life which he lives for his desire instead of doing with God.
Christians are the sheep who were saved hearing the voice of the shepherd Christ and having believed in his Gospel.
Sometimes good shepherd gives his life up to protect and save his flock.
Jesus Christ gave his life for us to be saved from sins and it's destruction. The shepherd Christ himself became the Lamb of God to expiate our sins (John1:29) and deliver us from the curse (Gal 3:13,14). He gave us eternal life abundantly and exuberantly.
