10 And while they were going to buy, the bridegroom came, and those who were ready went in with him to the marriage feast, and the door was shut. 11 Afterward the other virgins came also, saying, ‘Lord, lord, open to us.’ 12 But he answered, ‘Truly, I say to you, I do not know you.’ 13 Watch therefore, for you know neither the day nor the hour.
Deathbed repentance and faith upon Jesus does result in salvation as demonstrated by the thief on the Cross.
It’s not that it does not work, it’s that it’s a bad plan.
One cannot guarantee when and where they will meet their Maker either by passing from this life or Him physically returning to our world, but when He does, the gig is up.
Additionally, you cannot simply assume you will one day love Jesus enough to worship Him and follow Him if you do not want to do those things now.
It is not something you simply turn on and off like tap water.
All you have to do is turn a knob, but a lot of work went into making it so easy for you to get that water.
Do not build your house on sand and put off laying pipe and assume that someday when in thirst you turn the knob of your sink it will produce water.
And it will be too late.
