Matthew 22:30

“For in the resurrection they neither marry, nor are given in marriage, but are as angels in heaven.”

They failed to recognise the power of God because they limited Him to only being able to raise people in a way that would fit into earthly patterns. They did not accept the existence of ‘spirits'. But, Jesus points out, God was not so limited. For the truth is that in the resurrection men are ‘as angels in Heaven', that is, like the angels they are ‘spirits' (compare 1 Corinthians 15:44; 1 Corinthians 15:50. See Hebrews 1:7; Hebrews 1:14). They thus do not marry or engage in sexual practises. There is no need for reproduction in Haven, for none ever die. We saw at the commencement of this section that marriage was not to be seen as the sole basis on which men lived their lives (Matthew 19:12), and this is now being emphasised here. Marriage is to be seen as a secondary and earthly function, and while as such it is important here on earth, it will not be so in Heaven. Thus this immediately undercuts their whole argument, for it means that in Heaven she is not the wife of any. Note how this argument also emphasises the equality of men and women. The woman's temporary submission to man will also cease in Heaven, being replaced for all by the need for submission to God.
