Does GOD allow bad things to happen?

No, GOD doesn't allow bad things to happen, HE commands them to happen. The kingdom of GOD has a process by which HIS word is established in the earth. In HIS process, suffering leads to glory. Sorrow leads to joy. Affliction leads to growth and prosperity. Weakness leads to strength. GOD has ordained in the heavens, that bad things must happen, that HIS glory should be revealed in the earth.
