Is there a contradiction between Qur'an and reality about favor? surah 5:3

**My problem at understanding is about the completion of favor on believers.** If the favor of ALLAH is completed on believers how can believers now have good things? are those not favor of ALLAH? why? Like how can new believers get new good things if favor of ALLAH on believers was completed long ago? Emphasis mine and I made the part that I want to be answered as bold: > 5:3 Prohibited to you are dead animals, blood, the flesh of swine, and that which has been dedicated to other than Allāh, and [those animals] killed by strangling or by a violent blow or by a head-long fall or by the goring of horns, and those from which a wild animal has eaten, except what you [are able to] slaughter [before its death], and those which are sacrificed on stone altars, and [prohibited is] that you seek decision through divining arrows. That is grave disobedience. This day those who disbelieve have despaired of [defeating] your religion; so fear them not, but fear Me. This day I have perfected for you your religion **and completed My favor upon you** and have approved for you Islām as religion. But whoever is forced by severe hunger with no inclination to sin - then indeed, Allāh is Forgiving and Merciful. — Saheeh International
