What do you mean by "God's seed"? God is not a man, so He doesn't have "seed" of the biological sort.
Explain the birth of Jesus Christ from Mary without His seed.
What "seed" do you mean, then? What seed dwells in the born-again person that forces them to produce corresponding non-devilish "fruit"?
Those that love God with all their heart, mind, and strength, obey God naturally.
They are not
forced to obey Him who freed them from sin and given them eternal life.
"Being born again, not of corruptible
seed, but of incorruptible, by the
word of God, which liveth and abideth for ever." (1 Peter 1:23)
The seed is God's to gender after Himself.
As I've pointed out to you many times now, the Bible does clearly indicate that those in whom the "seed" of God resides DO sin.
1 Corinthians 3:1-3, 5, 6, 11.
Romans 6, 7, 8.
Galatians 3:1-3.
Ephesians 5:1-13.
1 John 1:8-10.
1 John 2:1-2.
Revelations 2-3.
Those who commit sin manifest the actions of those NOT born of God.
Those who adhere to the admonissions and exhortations of God's pastors and teachers show who matters most in their new lives.
And so on. Every NT injunction to born-again believers not to do something sinful is, obviously, an indicator that they are doing so. One does not have to command a sinless person to abstain from sin.
He does if he loves them enough to keep after them.
If you tell your kids not to use drugs, does that mean they are doing drugs ?
