It means your love for God must come first. It does mean to literally hate your family members or yourself it just means you can't love your family members and yourself more than God. God doesn't settle for second place in anybodies life. So if when it comes to your worship of the True God if something or someone takes the place of your worship of the true God then you can't be Jesus disciple. Jesus has always taught especially by example that God and your worship of him must come first and foremost in a person's life.
Exactly. This is why Jesus said,
For Moses said, Honor thy father and thy mother; and, He that speaketh evil of father or mother, let him die the death:
but ye say, If a man shall say to his father or his mother, That wherewith thou mightest have been profited by me is Corban, that is to say, Given
to God; ye no longer suffer him to do aught for his father or his mother; making void the word of God by your tradition, which ye have delivered: and many such like things ye do.
Mk.7:10-13
God doesn't need our help at all. People need our help. The only love God gets from us is when we're truly thankful for everything and if we are we'll let this world know it,
Even so let your light shine before men; that they may see your good works, and glorify your Father who is in heaven. Mt.5:16
You
are holy, Enthroned in the praises of Israel. Pa.22:3
Here's something I saw a few days ago,
the LORD said to Moses: “Tell Aaron your brother not to come at
just any time into the Holy
Place inside the veil, before the mercy seat which
is on the ark, lest he die; for I will appear in the cloud above the mercy seat. Lev.16:2
Aaron brings the cloud God sits on with him,
Then he shall take a censer full of burning coals of fire from the altar before the LORD, with his hands full of sweet incense beaten fine, and bring
it inside the veil.
“And he shall put the incense on the fire before the LORD, that the cloud of incense may cover the mercy seat that
is on the Testimony, lest he die. Lev.16:12-13
Incense being symbolic of the prayers of all the saints, it makes perfect sense.
