Eternal death is the absence of God.

Eternal death results from unrighteousness, spiritual uncleanness, and disobedience to God. God will not dwell with unrighteousness, spiritual uncleanness, or disobedience.

Eternal life enters us when we receive by faith the blood atonement made by the Lord Jesus Christ. God comes to us because of our receiving Christ. God imputes (ascribes) to us the righteousness of Christ. If it were not for our identification with the Lord Jesus, God would not accept our person; for God will not receive into His Presence those who are walking in sin. We now can stand in the Presence of God because of our acceptance of Jesus.

After initially receiving God’s Life by placing our faith in the atoning blood of Jesus we are to continue to look to Jesus moment by moment, interacting with Him, praying, meditating in the Scriptures, assembling with the saints, resisting the devil, giving, seeking ways in which we can build the Body of Christ.
We are to set aside our personal ambitions and give ourselves wholeheartedly to Christ and to His Gospel. We now are the servant of the Lord.

Jesus, through the Holy Spirit, through the ministries, through our environment and circumstances, proceeds to deliver us from the spirit of the world, from all unrighteousness, all spiritual uncleanness, and all disobedience to God.

As all sin and rebellion are driven from us, eternal life, love, joy, peace, and wisdom increase in us.

When all unrighteousness, uncleanness, and disobedience have been purged from us, and we have been filled with the Life of Christ, then we have arrived at the spiritual resurrection from the dead (Philippians 3:11). We have entered the promised-land rest of God.

Although the environment in which we live, including our sinful, dead body, still presses on us, our inner personality now is meeting God’s standard and He and His Christ are dwelling in us.

When Jesus returns He will complete our redemption by clothing our resurrected (or still living) flesh and bones with a body fashioned from the Life of God rather than from the dust of the ground.

If we have not walked in fellowship with Jesus such that we have been delivered from unrighteousness, uncleanness, and disobedience, if we have not allowed Jesus to save us, to deliver us from the works of Satan, then, when Jesus returns, we will receive an outer form that corresponds to our unchanged inner nature. We will reap corruption.

The unrighteous will receive the reward of unrighteousness.
The unclean will receive the reward of uncleanness.
The disobedient will receive the reward of disobedience.

For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad (II Corinthians 5:10)

Spiritual death is the separation from God of the spirit, the soul, and the body of man.

The "second death" is eternal spiritual death in an area of torment.

Wherever God is not present in the spirit realm there is an absence of love, of joy, of peace, of vitality, of wisdom, of knowledge, of hope, of growth.

Wherever God is not present in the material realm there is decay and finally ruin.

The most elementary definition of salvation is,to be spared the sentence of the second death.

To be "saved," in this rudimentary sense, says nothing about what we are. It speaks only of what we will not experience.

The fullest definition of salvation is,perfect, complete deliverance from all unrighteousness, all spiritual uncleanness, and all disobedience to God, the full growth of Christ in us, and eternal union with God through Christ.

It is important for the Christian to understand he cannot settle for elementary salvation. If God has called him to the royal priesthood he will be judged according to his high calling. He cannot live his life in the world in the hope he can neglect the fullness of the inheritance and still escape severe punishment.
