Last time i am doing this for you so pay attention:
1.) Future physical resurrection of the Saints = 1 Thess 4:13-18 , 1 Cor ch15 , 1 John 3:1-3 , Rev 2:10-11 & Rev 20:4-6
2.) CHRIST is the FIRST Resurrection = HE is the FIRSTFRUITS of Many BRETHREN = 1 Cor ch15
The firstruits of many Brethren ARISE at His Second Coming
But Christ has indeed been raised from the dead, the firstfruits of those who have fallen asleep.
21For since death came through a man, the resurrection of the dead comes also through a man.
A.) For as in Adam all die, so in Christ all
will be(future) made alive(physical resurrection-future)
B.) But each in his own turn:
Christ the firstfruits(Now/Today); then at His coming(future), those who belong to Him.
HIS First Coming and His Second Coming are
all inclusive of the FIRST Resurrection because it has TWO Distinct Parts
A.) Born-Again by the Spirit unto Eternal Life =
only our spirit/soul , the physical body dies
B.) NEW Glorified Bodies given to the Saints ONLY at His Second Coming = First Resurrection Completed for the Saints
Your Point #4 is not precisely spoken of in the Scripture except that Christ has completed ALL Things in HIMSELF necessary for Salvation.
Have you ever heard the expression - "Don't get ahead of your self'
God tells us what is sufficient for us RIGHT NOW/TODAY = the FUTURE belongs to HIM and we have no control or say over it
Peace
