I don't disagree about God being "good", but that also doesn't say much. God is not good because God measures up--in behavior or nature (or both)--to an external standard by which "good" is measured. Rather, God is good because God is God; God would be understood as "good" in whatsoever God chooses to do, regardless of how we might perceive the "goodness" of God's actions. So again, if God destroys the universe on a whim, meddles about in its processes to cause pain, or simply ignores it, God is good without qualification.
why is there talk of "knowing God" in the Bible if we anyway know/have Him?!, i.e., for example, what's the difference between believing in God of the world that is both good and evil and being/remaining disbelievers also under the same judgment of that God i.e. if both believers and non-believers know the same world full of good and bad things facing/undergoing the same ills?!, isn't the truth that to know God means to love your neighbor, because it is written "God is love"(1 John 4) and "all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself"(Gal 5)?!, and does the (show of) love include causing/infliction of evil/harm/affliction to/on the neighbor?!
Romans 13:8-10 "Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself. Love worketh no ill to his neighbour: therefore love is the fulfilling of the law."
so the believers should know God by believing in Him according to His Word/Gospel/Holy Commandments of faith, while the non-believers should know Him by adhering to the good treatment of the(ir) neighbor
then there is a true God high in the "heaven(s)" that never causes evil/harm/affliction to any person and exactly He is the one that should be known/followed/believed/worshiped/served, while the rest of the divine is more or less a manifestation of the "darkness" and should not be followed/believed/worshiped/served
1 John 1:1-10 "That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; (For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us; ) That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. And these things write we unto you, that your joy may be full. This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth: But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin. If(i.e. and if in such circumstances i.e. when we sin) we say that we have no sin(i.e. or if we, juxtaposing God and men, say that not the humans are sinful), we deceive ourselves, and the truth is not in us. If(i.e. but if in such circumstances) we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If(i.e. yet if in such circumstances) we say that we have not sinned, we make him a liar, and his word is not in us.",

1 John 5:20-21 "And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life. Little children, keep yourselves from idols. Amen.",

Galatians 4:8-9 "Howbeit then, when ye knew not God, ye did service unto them which by nature are no gods. But now, after that ye have known God, or rather are known of God, how turn ye again to the weak and beggarly elements, whereunto ye desire again to be in bondage?",
Ephesians 1:15-19 "I also, after I heard of your faith in the Lord Jesus, and love unto all the saints, Cease not to give thanks for you, making mention of you in my prayers; That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him: The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints, And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power",
Colossians 1:9-20 "we also, since the day we heard it, do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding; That ye might walk worthy of the Lord unto all pleasing, being fruitful in every good work, and increasing in the knowledge of God; Strengthened with all might, according to his glorious power, unto all patience and longsuffering with joyfulness; Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light: Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son: In whom we have redemption through his blood, even the forgiveness of sins: Who is the image of the invisible God, the firstborn of every creature: For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: And he is before all things, and by him all things consist. And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all things he might have the preeminence. For it pleased the Father that in him should all fulness dwell; And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven."
