If your son were to change his name, get plastic surgery and totally change his appearance, completely reject you and his earthly father, and never speak to you again…. Would that have any change in the DNA make up that is in him.
This is an easy question, because I provide the answer …. And the answer is
NO.
There is nothing he can do to change the DNA within him…
I can promise you that the spiritual seed of holy spirit within him is much greater than his physical seed.
Seed is seed ….it can never be changed or lost.
If he accepted Jesus Christ as his Lord and savior ….and only walked one day in light of the Word …. He has done more than all the unbelievers in the world.
People who try to make an argument for Christians losing their salvation have no biblical ground to stand on. I know the scripture that people use to say someone is not saved …. some of those mean the opposite of what they are trying project, and the others are way off base. People who claim we can lose salvation have their roots in a works doctrine …. Not Grace…. which is unmerited favor, which is how we are saved …
Old Testament believers had spirit upon (or in) them
conditionally based on their walk ….…we do not. We were saved by grace…PERIOD. There was nothing we did to earn it, and conversely, nothing we could do to lose it.
When God says that spirit (seed) abides forever.... that we are sealed until the day of redemption.... that is Gods promise to all of us in this administration of Grace.
1Pe 1:23 Being born again, not of corruptible seed, but of incorruptible, by the word of God, which liveth and abideth for ever.
Eph 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise,
Eph 4:30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.
