The temple of the Lord of Glory was at the top of a snow-white sacred mountain deep within his divine kingdom. That temple was built at the peak, with countless altars around it.
Hundreds of believers prayed there every day in the divine kingdom, with their power of faith being coalesced into divine crystals, appearing on the altars. Those altars were used by the Lord of Glory for amassing powers.
The Lord of Glory had no intention of using his power of the Source for creating angels.
The power of the Source was the foundation of the divine kingdom, yet believers were people that could be recruited from a myriad of planes and brought to the divine kingdom. When the powers of the Source on those believers had been completely drained, that was when they would meet their end.
The more powerful the power of the Source of a believer, the longer they would be able to live. None of that had anything to do with the Lord of Glory himself.
