1 Corinthians 15:50-52
1 Corinthians 15: 50 to 52
50 But I tell you this, brethren, flesh and blood cannot [become partakers of eternal salvation and] inherit or share in the kingdom of God; nor does the perishable (that which is decaying) inherit or share in the imperishable (the immortal).
51 Take notice! I tell you a mystery (a secret truth, an event decreed by the hidden purpose or counsel of God). We shall not all fall asleep [in death], but we shall all be changed (transformed)
52 In a moment, in the twinkling of an eye, at the [sound of the] last trumpet call. For a trumpet will sound, and the dead [in Christ] will be raised imperishable (free and immune from decay), and we shall be changed (transformed).
