How do I qualify for resurrection after I die?
The Lord Jesus Christ preached the Gospel of the Kingdom of God.
Mark 1:14 Now after John was put in prison, Jesus came to Galilee, preaching the gospel of the kingdom of God,
After his resurrection Jesus gave his disciples a commission:
Mark 16:15 And He said to them, "Go into all the world and preach the gospel to every creature. 16 He who believes and is baptized will be saved; but he who does not believe will be condemned.
Philip preached the gospel of "the things concerning the kingdom of God, and the name of Jesus Christ". Those who believed were baptised.
Ananias told Saul (Paul) to be baptised to wash away his past sins.
From this we conclude:
After baptism we must live a new life, by the commandments of Jesus.
The new life requires us to meet regularly with fellow believers to share bread and wine in remembrance of Jesus’ sacrifice.
If we do these things we will be raised from the dead when Jesus returns to set up the Kingdom of God.
1 Corinthians 15:20-28 But now Christ is risen from the dead, and has become the firstfruits of those who have fallen asleep. 21 For since by man came death, by Man also came the resurrection of the dead. 22 For as in Adam all die, even so in Christ all shall be made alive. 23 But each one in his own order: Christ the firstfruits, afterward those who are Christ’s at His coming. 24 Then comes the end, when He delivers the kingdom to God the Father, when He puts an end to all rule and all authority and power. 25 For He must reign till He has put all enemies under His feet. 26 The last enemy that will be destroyed is death. 27 For "He has put all things under His feet." But when He says "all things are put under Him," it is evident that He who put all things under Him is excepted. 28 Now when all things are made subject to Him, then the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.
I hope this helps.
God bless,
