Because it's what scripture teaches.
It is God who gives food to ALL. That's everyone. Every man get's his full.
Unfortunately not. The gate is wide and the way is broad that leads to destruction, and there are
many who go by it. The gate is narrow and the way is difficult which leads to life, and there are
few who find it. Enter by the narrow gate. Everyone who does not bear good fruit is cut down and thrown into the fire. Not everyone who says, 'Lord, Lord,' shall enter the kingdom of heaven. The Lord will declare to them, 'I never knew you; depart from Me, you cursed, you who practice lawlessness, into the everlasting fire prepared for the devil and his angels.'
13 "Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it.
14 Because narrow is the gate and difficult is the way which leads to life, and there are few who find it.
15 "Beware of false prophets, who come to you in sheep's clothing, but inwardly they are ravenous wolves.
16 You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles?
17 Even so, every good tree bears good fruit, but a bad tree bears bad fruit.
18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit.
19 Every tree that does not bear good fruit is cut down and thrown into the fire.
20 Therefore by their fruits you will know them.
21 "Not everyone who says to Me, 'Lord, Lord,' shall enter the kingdom of heaven, but he who does the will of My Father in heaven.
22 Many will say to Me in that day, 'Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?'
23 And then I will declare to them, 'I never knew you; depart from Me, you who practice lawlessness!'
41 Then He will also say to those on the left hand, 'Depart from Me, you cursed, into the everlasting fire prepared for the devil and his angels: (Matthew 25:41)
Matthew 5:
43Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy.
44But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you;
45That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust.
46For if ye love them which love you, what reward have ye? do not even the publicans the same?
47And if ye salute your brethren only, what do ye more than others? do not even the publicans so? 48Be ye therefore perfect, even as your Father which is in heaven is perfect.
No relevance here. God in His mercy causes the sun to rise every day over the whole world. That doesn't mean that everyone is saved.
