Simple. Jesus referred to "this age" (40 years prior to AD70) and to the "age to come" in which His disciples would receive their rewards and eternal life.
29 So He said to them, "Assuredly, I say to you, there is no one who has left house or parents or brothers or wife or children, for the sake of the kingdom of God, 30 who shall not receive many times more in this present time, and in the age to come eternal life."
That the "age to come" is after the second coming of Christ and the resurrection of the body at His coming is proven a couple of chapters later.
34 Jesus answered and said to them, "The sons of this age marry and are given in marriage. 35 But those who are counted worthy to attain that age, and the resurrection from the dead, neither marry nor are given in marriage; 36 nor can they die anymore, for they are equal to the angels and are sons of God, being sons of the resurrection.
Perhaps Chuck Doughty should check to see whether Christians can marry now and procreate. If so, we are still in the same "age" as Jesus was when He said this.
Furthermore, Jesus put the "harvest" and casting of the tares into the furnace of fire at "the end of this age." (prior to AD 70).
40 Therefore as the tares are gathered and burned in the fire, so it will be at the end of THIS age. 41 The Son of Man will send out His angels, and they will gather out of His kingdom all things that offend, and those who practice lawlessness, 42 and will cast them into the furnace of fire. There will be wailing and gnashing of teeth. 43 Then the righteous will shine forth as the sun in the kingdom of their Father. He who has ears to hear, let him hear!
If Chuck Doughty wants to maintain his "Jewish age" and "Christian age," he will have to place the resurrection of the dead and rewards of believers in AD70, as well as the harvest and casting unbelievers into the fire at the "end of this age" in AD70. He should also denounce marriage if we are now living in the "age to come." Good luck with that.
