do you want to know who is correct?
It is the writer of the Psalm who is correct. Why? Because he was inspired, or directed by holy spirit, to write what he wrote. The bible presents Gods thoughts on the matter, not our own.
You can liken religious beliefs and opinions to a smorgasbord of food prepared by us and offered to God. We prepared them as offerings to God for worship. But how many of our offerings does he actually like? What a disaster it would be for us if we put so much effort and time into preparing all these dishes, and God comes and examines them and says
"no sorry, i dont like your dish...nor do this persons dish.... Im not going near Johnny's dish... her dish over there is repulsive to me... no, im alergic to Peters dish.."
now we have a big problem because all these forms of worship are unacceptable to him. Where does that leave us?
The fact is that God has already told us what dish to prepare, he has told us the ingredients and how he likes it. But unfortunately we continue to bake our own pies.
Its good to have people in our life whom we can trust. But there is also God whom we can trust and his word encourages us to do so:
Psalm 118:
8 It is better to take refuge in Jehovah
Than to trust in humans.
Psalm 40: 4 Happy is the man who trusts in Jehovah...'
Proverbs 3:5 Trust in Jehovah+ with all your heart,
And do not rely* on your own understanding.
In all your ways take notice of him,
And he will make your paths straight
Our life is not supplied to us by people. It is sustained by God himself therefore we are dependent on God for our very existence and our salvation is completely in his hands.... so putting our trust in him is a worthwhile goal.
You've stated that you dont believe a Supreme God exists but your family do.
Logically, two opposing views cannot both be right. Either God exists or he doesnt. Both cannot be correct.
But this is a good example of that smorgasbord of beliefs. We offer the dishes we choose to offer. In the end, God will decide on what he likes and what he doesnt. At least he gives us the option of choosing.
