Abraham is favoured, yes, for his good conduct, for his being favoured depended on his faith, which was not only God's merit but his also, for otherwise, if only God's merit, then the expression "Abraham believed and it was accounted him to a righteousness" (Genesis 15:6) loses any logic and sense.
Thus, what does it mean? Is there favouritism in God for that reason, I mean for the reason that some people chose to make a motion towards God out of free will? Does not God love all? Yes! If it is stupid to think that the sun enlightens those lying on a beach differently, choosing the people's bodies out of some whim, so it is twice as stupid to think that God loves some more some less (cf. Matthew 5:45), for He loves all uniquely and infinitely. In the mentioned Matthew 5:45 Jesus tells his disciples to be like Himself and, analogously to the sun which does not distinguish the bodies, but enlightens all, good and evil likewise, to love all, good and bad, friends and enemies, indistinguishably, which only would make them like God who is such to all, good and bad. Now, if God commands His top-creatures, the only ones bearing His image and likeness, to be unprejudiced and distinguish not in loving, how utterly stupid it is even to hypothetically permit such a thought that the Giver of this infinite law of love Himself is prejudiced!
That there is no prejudice in God, Paul clearly states: "There is no partiality in God" (Romans 2:11), but does this Pauline oracle, inspired by Holy Spirit, augment in any manner such a simple insight, which even Greek philosophers guessed by sincerely following logic and dialectic, for Plato and Aristotle, Heraclitus or Pythagoreans, to say nothing about the great Parmenides, would also say unflinchingly that it is impossible for any trace of favouritism to abide with the First Principle of the universe.
But, surely, not all understand, respect and reciprocate with the infinite love of God, which is not God's fault, to be sure.
So, to conclude, those who reciprocate in their freedom with God's love and do God-ly things in faith, they by this very act are favoured by God in whom there is no favouritism in the sense of a certain inscrutable and beoyond-human-understanding whim that He loves or favours some persons more and some persons less notwithstanding those person's conduct and free choices. That God loves all and wants all to be saved is said by the Holy Spirit through Paul in 1 Timothy 2:4. Now, those who still claim that there is some sort of favouritism in God even with His all-mankind-inclusive love, then such theologians, who to me do not deserve this honourable name, fall into a schizophrenia that God loves all but favours some, as if there is a double activity in God - a) loving and b) favouring. But begone with this, unless, of course, we want to embrace heresy of Jansenists, Jan Kalvin and similars.
I was said by one of the BH-siters to stay respectful, and I answered that I am 100% respectful to all heretics, but not the heresy they follow. Respectful we should be to truth, if we are respectful at detriment of truth, and thus not call heresy that what it is, i.e. heresy, then we extinguish Holy Spirit in us, which Paul said we should not do (1 Thesalonians 5:19).
