Many have beliefs and there are doctrines which preach along the lines, saying: “Once saved always saved”.
Jesus says: “No man, having put his hand to the plough, and looking back, is fit for the Kingdom of God” (Luke 9:62). “But he that shall [ENDURE UNTO THE END], the same shall be saved” (Matthew 24:13).
Once we come to the knowledge of the Truth by the word of God, we are not to look back on this earth to the lusts, pleasures, and pride of life, in other words, the pollutions of this world. Peter, a disciple of Jesus said:
“For if after they have escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning” (2 Peter 2:20).
“Now the just shall live by faith: but if any man draws back, my soul shall have no pleasure in him. But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul” (Hebrews 10:38–39).
“Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God. But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin. For we are made partakers of Christ, if we hold the beginning of our confidence stedfast unto [THE END]” (Hebrews 3:12-14).
