You are doing two things here, you are ignoring the fact that God created life and is outside of our known universe which includes time; the other is that you are asking the Christian viewpoint on the actions of God. It doesn't matter if you agree that God has determined how long one's life lasts on this planet, and it makes no difference if you don't agree that life once gone here goes on afterwards in another location. God is not limited to gravity for instance but that doesn't mean that the laws that He created for this planet are not absolute and objective. If I jump from a 12 story building, it is absolute and can be shown completely objectively that I will fall down and not up. The same with God's rules of morality. God has the ability and motivation to make sure His decisions to take a life from this location to His can be done in a merciful way. For you, life here is all there is and so you don't understand that life from here to there is like walking through a door to the other side. We as humans, didn't create life, have not determined (or are even able) to determine how long a person's life is to be. We don't have the authority, the pertinent information needed to determine how long a person lives and have no right to take life from another, unless we have pertinent information as in the case of murder.
Here is exactly what you said: You've said repeatedly that God is allowed to kill infants, and that humans are not. Do I need to go dig up the quotes? Why are you being so dishonest?
That is saying that God is equal to man. If not explain.
Why would it be immoral for God to determine how long a person will live? He created life, controls the timeline of the universe including each life on earth, so why would it be immoral?
Bob is a human being and has no way of knowing what is "best" or how or when another person's life should be taken. God has the entire timeline from the beginning of time until the end of time to know what each person will do and has determined the length of time one is on earth, obviously we don't have that information.
Seriously?
That is interesting:
1 Corinthians 2:14 The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit.
2 Corinthians 4:3-4 If the Good News we preach is hidden behind a veil, it is hidden only from people who are perishing. Satan, who is the god of this world, has blinded the minds of those who don’t believe. They are unable to see the glorious light of the Good News. They don’t understand this message about the glory of Christ, who is the exact likeness of God.
How would you know?
