God has provided us, the human race, with His grace and He planned this even before He created our world. He has known which of us would accept Jesus since then, even though His grace and our atonement was paid for by Jesus on the cross two-thousand years ago. Jesus paid the price for all of us even though He knew there would be many who would not accept Him as their Savior.
You can know God and His purpose for your life better if you read His Word. The more you know Him and His Word the better you will be able to stand against the devil until Jesus comes.
