“But Noah found grace in the eyes of the Lord . . . . .” (Genesis 6:8)
Noah and his family were saved from the flood by the grace of God, but that salvation was temporary because he and his family eventually died like everyone does. Death is God’s will for humanity in this present evil age. But it is also God’s WILL that humanity be saved out of death - again by His GRACE.
"As in Adam all die, even so, in Christ, all shall be made alive." (1 Corinthians 15:22)
"For the wages of sin is death, but the free gift of God is eternal life..." (Romans 6:23)
“For the grace of God has appeared, bringing salvation to all humanity…” (Titus 2:11)
“For by grace are you saved through faith…it is the gift of God…” (Ephesians 2:8)
“For this is good and acceptable in the sight of God our Savior; Who will have ALL humanity be SAVED, and to come unto the knowledge of the truth. For there is one God, and one mediator between God and humanity, the man Christ Jesus; Who gave himself a ransom FOR ALL, to be testified in due time. Whereunto I am ordained a preacher, and an apostle, (I speak the truth in Christ, and lie not;) a teacher of the Gentiles in faith and verity.” (1 Timothy 2:3-7)
"Thus also is the resurrection of the dead. It is sown in corruption; it is roused in incorruption. It is sown in dishonor; it is roused in glory. It is sown in infirmity; it is roused in power. It is sown a soulish body; it is roused a spiritual body...we all shall be changed, in an instant, in the twinkle of an eye, at the last trump. For He will be trumpeting, and the dead will be roused incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal put on immortality. Now, whenever this corruptible should be putting on incorruption and this mortal should be putting on immortality, then shall come to pass the word which is written, Swallowed up was Death by Victory." (1 Corinthians 15:42-45; 51-54)
It is OK to mourn the death of a loved one, but never forget our blessed expectation (hope) - it will be glorious!
