An example of a ‘descriptive’ passage of scripture would be 1 John 2:3-4. By this we know that we have come to know Him, (already know Him/already saved/demonstrative evidence) if we “keep” (Greek word “tereo” - guard, observe, watch over) His commandments. 4 The one who says, “I have come to know Him,” and does not keep His commandments, is a liar, and the truth is not in him. So the former is descriptive of believers and the latter is descriptive of unbelievers. You use the word “believer” too loosely.
How did they get the power to prophesy, cast out demons and perform miracles in Jesus' name if Jesus "never knew" them?
There are false prophets who prophecy in the name of Jesus and even make false prophecies. Also, Satan may grant the power to one of his agents to cast out demons from another of his agents in order to gain attention and loyalty from an audience for his evil agenda. In Matthew 10:1, we also see that Jesus gave His 12 disciples power over unclean spirits, to cast them out, and to heal all kinds of sickness and all kinds of disease. This would include Judas Iscariot, yet Jesus referred to Judas Iscariot as an
unbelieving, unclean devil who would betray Him! (John 6:64-71; 13:10-11). Apparently, Judas believed that Jesus' name has the power to cast out demons but did not truly believe in His name (John 1:12) and become a child of God, but instead was the son of perdition. (John 17:12)
Do you think "I never knew you" might be a figure-of-speech which means something like, "I disown you, therefore it's as if I never knew you"?
No. Jesus did not say I once knew you but don’t know you anymore. The Greek word “never” is oudepote. This is a very strong Greek word meaning “not ever, not even ever.”
You really need an explanation for 1 John 3:9-10? - No one who is born of God practices sin, because His seed abides in him; and he cannot sin, because he is born of God. 10 By this the children of God and the children of the devil are obvious: anyone who does not practice righteousness is not of God, nor the one who does not love his brother. Can you not see the contrast here between children of God and children of the devil?
It is also the "Father's will" that we OBEY his Son and keep his commandments:
"If you love me, you will KEEP MY COMMANDMENTS" (John 14:15).
Yes, AFTER we have been saved. Yet people who Jesus NEVER knew were NEVER saved so these many people in Matthew 7:21-23 failed to do the Father’s will of believing in Jesus unto salvation. (John 6:40) It’s also not the Father’s will for us to keep the commandments as a legalistic prescription for salvation. We are not saved by works or law keeping. (Romans 4:2-6; 10:1-4; Ephesians 2:8,9; Galatians 2:16; Titus 3:5; 2 Timothy 1:9 etc..).
Now there is a difference between doing God's will IN ORDER TO BECOME SAVED:
John 6:40 - For
my Father’s will is that everyone who looks to the Son and
believes in him shall have eternal life, and I will raise them up at the last day.
AND doing God's will AFTER WE HAVE BEEN SAVED:
1 Thessalonians 5:14 - Now we exhort you, brethren, warn those who are unruly, comfort the fainthearted, uphold the weak, be patient with all. 15 See that no one renders evil for evil to anyone, but always pursue what is good both for yourselves and for all. 16 Rejoice always, 17 pray without ceasing, 18 in everything give thanks;
for this is the will of God in Christ Jesus for you.
In fact, if a believer doesn't keep his commandments, he is "a liar, and the truth is in him" (1 John 2:3-5) ... which means he is not in Christ ... we means he has no hope of salvation.
Here you go again using the word “believer” too loosely and confusing descriptive with prescriptive.
And here's the Father identifies his "offspring" ...
"those who KEEP THE COMMANDMENTS OF GOD and bear testimony to Jesus." (Rev 12:17).
Identifies. Descriptive. Demonstrative evidence.
And just in case you missed it the first time, here's how the Father identifies his "saints" ...
"those who KEEP THE COMMANDMENTS OF GOD and the faith of Jesus. (Rev 14:12)
I did not miss it and I understand the difference between genuine believers and make believers. BTW please explain to me WHICH commandments that you believe are in view here and also what it means to KEEP them. Are the 10 commandments under the old covenant of law in view here? Does “keep” mean flawlessly obey them? Have you flawlessly obeyed them 100% of the time?
