Just had a sobering thought. We put so much importance on feelings and experiences in this culture. But a spiritual experience does not automatically guarantee eternal security.
People saw Jesus perform miracles and then those same people crucified Him. Or consider Judas. He was with Jesus on a daily basis. He had more reason to believe than most. And yet he sold Jesus out. Even the demons believe that Jesus is real.
The believer and unbeliever can both have spiritual experiences. It makes sense that God would reveal Himself to everyone. The Word of God states that He wishes none to perish.
And yet we all sin. So what separates a Peter from a Judas? What makes me different than Judas? Than Saul? Than Pharaoh? They all had spiritual experiences. We certainly cannot rest our eternal security merely on the basis of having a spiritual experience.
“You believe that there is one God. You do well. Even the demons believe — and tremble! But do you want to know, O foolish man, that faith without works is dead?” (James 2)
“Therefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling; for it is God who works in you both to will and to do for His good pleasure.” (Philippians 2)
“Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life, and there are few who find it.
“Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves. You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? Even so, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Therefore by their fruits you will know them.
“Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’” (Matthew 7)
“Do you not know that a little leaven leavens the whole lump? Therefore purge out the old leaven, that you may be a new lump, since you truly are unleavened. For indeed Christ, our Passover, was sacrificed for us. Therefore let us keep the feast, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.” (1 Corinthians 5)
