Instead of having a plan for our redemption which the vast majority of the world's population would fail based on Christian teaching, why didn't God devise a plan where we wouldn't sin which would guarantee safety for the vast majority of the world's population. Afterall isn't God supposed to be able to do anything/everything and isn't He supposed to be merciful and loving? Just a thought.
When God created man he give man free will, didn't he? Here is verse that depict just that. Joshua 24:14-15
14 Now therefore fear the Lord, and serve him in sincerity and in truth: and put away the gods which your fathers served on the other side of the flood, and in Egypt; and serve ye the Lord.
15 And if it seem evil unto you to serve the Lord, choose you this day whom ye will serve; whether the gods which your fathers served that were on the other side of the flood, or the gods of the Amorites, in whose land ye dwell: but as for me and my house, we will serve the Lord.
Whatever you decide to do it's your free will. Just choose wisely. Only a thought!
