the Bible's Perspective

Deuteronomy 11:26-27Behold, I set before you today a blessing and a curse: the blessing, if you listen to the commandments of the LORD your God, which I command you today;
Deuteronomy 28:1It shall happen, if you shall listen diligently to the LORD your God’s voice, to observe to do all his commandments which I command you today, that the LORD your God will set you high above all the nations of the earth.
Deuteronomy 28:13The LORD will make you the head, and not the tail. You will be above only, and you will not be beneath, if you listen to the commandments of the LORD your God which I command you today, to observe and to do,
Deuteronomy 30:19I call heaven and earth to witness against you today that I have set before you life and death, the blessing and the curse. Therefore choose life, that you may live, you and your descendants,

the Quran's Perspective

Al-Baqara (The Cow) 2:2-5This is the Scripture whereof there is no doubt, a guidance unto those who ward off (evil). Who believe in the Unseen, and establish worship, and spend of that We have bestowed upon them; And who believe in that which is revealed unto thee (Muhammad) and that which was revealed before thee, and are certain of the Hereafter. These depend on guidance from their Lord. These are the successful.
