“Born of water and Spirit”(Jn 3:5). When Jesus talked about regeneration to Nicodemus, he clearly referred to Ezekiel 36:24-27, indicating that regeneration is resulted from water (a metaphor for the written Word of God, the Bible) and Holy Spirit. His teaching clearly indicates how the remnants in OT were saved. The good example is how Ezekiel was saved. According to Jesus’ teaching,  anyone who has the Spirit of Christ can see the kingdom of God (Jn 3:3) and can enter the kingdom of God (Jn 3:5). We can see “the word of the LORD came to Ezekiel the priest, the son of Buzi, in the land of the Chaldeans by the Chebar canal, and the hand (also translated as Spirit) of the LORD was upon him there.”(Ezek 1:3). The Lord spoke to Ezekiel (Ezek 1:28;2:1-8; 3:1-11,16-21) and the Spirit dwelled in him and lifted him up (Ezek 3:12-14; 22-24).  Then he was able to see the Kingdom (Ezek 1:28; 3:23) and enter the kingdom (Ezek 1:28; 3:1-3, 15,23). He is the one who has been delivered from one realm, the realm of sin and death, and has been transferred to the realm of Christ’s Spirit, which is life. When he saw the kingdom, he fell on his face and started eat the scroll, he was humbled and ready to serve as a suffering prophet. He saw the King, son of God, would leave his heavenly throne, which is mobile, moving with lightning speed across the sky, and come down to the earth as son of man dwelling in his captured people, give up his freedom for the freedom of the chosen people who are bonded with sin, serve them as a suffering prophet (Jn1:14, Phl2:6-11). Since the Spirit of Christ dwelled in him and lifted him up, he was able to be imitator of Christ. He was a new creature in Christ’s image. He stood in the gap between an angry God and a sinful people as Christ did. He spoke prophecies to the dry bones (preaching God’s words to spiritual dead people) and the wind (prayer to Holy Spirit) (Ezek 37:3-14). That’s how the dry bones were resurrected. People in NT are saved in the same way. The elders in OT had to devoted themselves “to prayer and to the ministry of the word”(Acts 6:4). Because that’s the way how God save his elected ones through his servants.  Peter said that we are “born again, not of perishable seed, but of imperishable, through the living and enduring word of God” (1 Peter 1:23). He is using the facts of sex as an image, saying that the Word of God operates on our heart as the male sperm does on the ova in the uterus of a woman. The uterus is our heart; the ova is faith. The sperm of God’s Word penetrates our hearts to bring forth the life of eternity. Paul says “let the elders who rule well be considered worthy of double honor, especially those who labor in preaching and teaching”(1Tim 5:17).  Luke mentions 3 times in Acts “word of God continued to increase and the number of the disciples multiplied greatly” (Acts 6:7;12:24;19:20). Very often, our Christian forgot an essential truth, i.e. Christ is the Word who became flesh(John 1:1,14) . People who exalt Christ devote themselves to the ministry of the word as Apostles and those elders did (Acts 6:4; 1Tim 5:17).  A water-down or twisted gospel would result in no growth of the church, just like low sperm count or abnormal sperm would result in infertility.  God’ servants have no right to be silence on biblical truth (Ezek 3:16-21; 1Cor 9:16-17; 1Tim 4:16). The way that God saves his people in both OT and NT is the same.
