The bible teaches that God did create evil.
Isaiah 45:7 -
The One forming light and creating darkness, Causing well-being and creating evil; I am the LORD who does all these.
Proverbs
16:4 -
The LORD has made everything for its own purpose, Even the wicked for the day of evil.
Why, because it pleases Him.
Our God is in the heavens: he hath done whatsoever he hath pleased (Psa. 115:3).
He doeth whatsoever pleaseth him (Eccl. 8:3).
Thou, O Lord hast done as it pleased thee (Jonah 1:14). Whatsoever the Lord pleased, that did he in heaven, and earth, and in the seas, and in all the deep places (Psa. 135:6).
He does all his pleasure (Isa. 46:10; Isa. 44:24-28; Eph. 1:5,9; Phillipians 2:13).
Man can’t accept this fact.
My thoughts are not your thoughts, neither are your ways my ways. As the heavens are higher than the earth, so are my ways higher than your ways and my thoughts higher than your thoughts (Isa. 55:8,9)
It would be a redundant statement to give thanks for only the good things God wills.
1Th 5:18 -
in everything give thanks; for this is God’s will for you in Christ Jesus.
