1 Peter 1:3 Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,
1 Peter 1:4 To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
1 Peter 1:5 Who are kept by the power of God through faith unto salvation ready to be revealed in the last time.
1 Peter 1:6 Wherein ye greatly rejoice, though now for a season, if need be, ye are in heaviness through manifold temptations:
1 Peter 1:7 That the trial of your faith, being much more precious than of gold that perisheth, though it be tried with fire, might be found unto praise and honour and glory at the appearing of Jesus Christ:
1 Peter 1:8 Whom having not seen, ye love; in whom, though now ye see him not, yet believing, ye rejoice with joy unspeakable and full of glory:
1 Peter 1:9 Receiving the end of your faith, even the salvation of your souls.
Jesus died on the cross to make it possible that salvation is reserved in Heaven for us, "though now for a season, if need be, ye are in heaviness through manifold temptations: That the trial of your faith, being much more precious then gold". It is not about boasting, it is about standing against evil and proving our faith. If God wanted to just "predestinate" us, he just wouldn't give us free will. But did God want a robot worshipping him for all eternity, or a living soul? To have real love, the person must choose you for themselves even when things are bad.
I choose the Holy Father through Jesus Christ, and I will strive to prove my love by my actions so I can be with my Father. I am a weak sinful human that can not do it myself, so I give all glory and credit to the Father for helping me through this life.
Those that are against works and obedience are just spoiled children, "I do not need to prove myself to God, going to Heaven is my birthright and God will give it to me without me doing anything in return!" Time to wake up: the Father does not owe you anything, he does not need to grovel to your demands. You are the servant, the Father is the master. If a servant does not do their work, they are worthless and thrown out on the street. If a servant does not obey the master, they are worthless and thrown out on the street.
Do not put your self above who you are; work and obey...if you are too proud, your delusions of automatic eternity is your only reward.
