God is merciful and not just merciful to some and unmerciful to others.
If God is only merciful to some than He is not merciful Daniel 9:9 The Lord our God is merciful and forgiving, even though we have rebelled against him;
Ro. 11:32 For God has bound everyone over to disobedience so that he may have mercy on them all.
In this verse “everyone” is disobedient, for it certainly is not just the elect that are disobedient, so God has (or is extending) mercy on everyone who is disobedient.
So God is not as you say only “having mercy on some”.
The problem is not with God lacking any Love (Love being: mercy, grace, charity, forgiving and kind), but it is with man just humbly accepting God’s Love, mercy, grace, charity, forgiveness and kindness. Accepting a gift is not work by the Biblical definition of work, and is not something worthy of a reward.
You do not want to make God’s lack of Love the reason for humans going to hell, when the problem is man’s lack of acceptance.
You have to trust (have faith) enough to accept God's charity in the form of forgiveness as pure charity.
The lowliest mature adult on earth can humbly accept help from a benevolent Creator, so saving faith is a humbling activity, with most refusing to be humble themselves to that degree.
So why is any kind of faith needed?
With God so benevolent and nothing being required of the believer except trust why have "saving faith" rather than just pure benevolence on God's part saving everyone? What's the point of asking for or demanding trust from the recipient of salvation when nothing like obedience, goodness, holiness etcetera is needed, is any of it even asked for?
I ask this because scripture sure looks as if holiness is needed: Strive for peace with everyone, and for the holiness without which no one will see the Lord. (Hebrews 12:14). And obedience too seems important:
And Samuel said, Has the Lord as great delight in burnt offerings and sacrifices,
as in obeying the voice of the Lord?
Behold, to obey is better than sacrifice,
and to listen than the fat of rams.
(1 Samuel 15:22)
What is the motive for doing all this?
Does obedience without Godly type Love beneficial 1 Cor. 13:1-4?
If you have Godly type Love will that not compel you to do good stuff?
What is there to gain from doing good stuff, besides not giving away, what has already been given?
Faith is need to help the willing individual fulfill their earthly objective.
are not praising Him.
Everything needs to start with the objective.
The differences and issues begin with misunderstanding of the objective. Most Christians like: Man’s objective is to “bring glory to God” and have scripture references to support that objective, but a person can take any commandment or direction of God given in scripture and have Biblical support for call that command: “Man’s Objective”. We are certainly commanded to do that command, so why is it not man’s objective?
There are the two superior commands which all other commands are subordinate to and combined would be like: “Love God (and secondly others) with all your heart, soul, mind, and energy.” That appears to be man’s “Mission Statement”. The huge problem with fulfilling that “Mission Statement” is the fact that the “Love” needed would have to be huge, way beyond anything man could develop, learn, deserve, earn, pay back, be instinctive to man, or somehow just be forced upon humans.
Thus, the reason you have free will, is because it is required for you to complete your earthly objective.
This messed up world which includes satan roaming around is not here for your pleasure, but to help each of us to become like God Himself in that you have the unique, unbelievable Godly type Love (God himself is Love).
There are just somethings even an all-powerful Creator cannot do (there are things impossible to do), like create another Christ, since Christ has always existed, the big impossibility for us is; create humans with instinctive Godly type Love, since Godly type Love is not instinctive. Godly type love has to be the result of a free will decision by the being, to make it the person’s Love apart from God. In other words: If the Love was in a human from the human’s creation it would be a robotic type love and not a Godly type Love. Also, if God “forces” this Love on a person (Kind a like a shotgun wedding) it would not be “loving” on God’s part and the love forced on the person would not be Godly type Love. This Love has to be the result of a free will moral choice with real alternatives (for humans those alternatives include the perceived pleasures of sin for a season.)
Read the story of the Prodigal Son in Luke 15, the young son was generously given more then he could handle (like most of us today), which the father would realize. The prodigal son returned to his father, not out of “Love”, but selfishly wanting a job he did not deserve or should even ask for. Just because the son became just willing to accept pure undeserved charity from the father he hated, allowed the father to shower him with gifts. God is that way with you.
God has created beings to shower them with the greatest gifts possible, the greatest gift being having a Love like His.
If there is this Creator of the universe out there, His “creations” could not really “do” anything for Him, so this Creator would have to be seen as a Giver (Unselfish Lover) and not trying to “get” something from His creation.
Why would God have a totally unselfish type of Love, since He personally would not get anything out of it? If God’s “Love” is some kind of knee jerk reaction, then it is really meaningless (something like; gravity which is nice to have, but everyone automatically has it). God Loves us in spite of what we have done, who we are or what we will do, so it has to be by His choice.
God would create the right universe for the sake of the individuals that will accept His gift (the most powerful force [Love] in all universes, since that force [Love] compels even God to do all He does) and thus the willing become like He is (the greatest gift He could give).
What keeps the all-powerful Creator from just giving whatever He wants to his creation, eliminating the need for free will and this earthly time.
This Love is way beyond anything humans could develop, obtain, learn, earn, pay back or ever deserve, so it must be the result of a gift that is accepted or rejected (a free will choice).
This “Love” is much more than just an emotional feeling; it is God Himself (God is Love). If you see this Love you see God.
All mature adults do stuff that hurts others (this is called sin) these transgressions weigh on them, burden them, to the point the individual seeks relief (at least early on before they allow their hearts to be hardened). Lots of “alternatives” can be tried for relief, but the only true relief comes from God with forgiveness (this forgiveness is pure charity [grace/mercy/Love]). The correct humble acceptance of this Forgiveness (Charity) automatically will result in Love (we are taught by Jesus and our own experience “…he that is forgiven much will Love much…”). Sin is thus made hugely significant, so there will be an unbelievable huge debt to be forgiven of and thus result in an unbelievable huge “Love” (Godly type Love).
