First and foremost people need to remember, or if they never knew, come to know that the entire New Testament was written for those that had already asked Jesus Christ to be their Savior and Lord.
Even though saved and born again anew in the Holy Spirit, we are all still tempted to sin. For Satan takes great pleasure in turning those that have chosen Christ to falter and fall away as is born out in the second chapter of the second letter of Peter.
It must also be remembered that Peter is not the only one to speak of those of the Body falling into “death.” James did as well:
James 1:11 – For the sun is no sooner risen with a burning heat, but it withereth the grass, and the flower thereof falleth, and the grace of the fashion of it perisheth: so also shall the rich man fade away in his ways. 12 Blessed is the man that endureth temptation: for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him. 13 Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, neither tempteth he any man: 14 But every man is tempted, when he is drawn away of his own lust, and enticed. 15 Then when lust hath conceived, it bringeth forth sin: and sin, when it is finished, bringeth forth death.
Understand fully that by allowing temptation of sins to have power over you, which places the desire and the lust of the sin, to outweigh your love for God that it will result in your separation from God forever which the true death is.
Millions today think themselves alive in God, but in reality they are dead to Him, for to them the sin is more important than their Creator. For we are in the times of the lukewarm, which is the sign of the soon return of our Savior the Lord Jesus Christ.
His return though will be presided by trials, tribulations, and great suffering. Numbered amongst those suffering will be those that thought themselves alive in Christ, but on that glorious, yet horrifying day they will see some about them called into heavens to meet Jesus in person, yet they will still be here. Shocked and bewildered, not fully understanding that is was their choice that left them here upon this planet. Why? Because they choose that which is here over the manifest glory of God and His Son, our Lord and Savior Jesus Christ.
