For one of the Gods may have so loved the world, that He gave His only begotten Son, that whosoever believes in him should not perish, but have everlasting life

For God so loved the world, that He gave His only begotten Son, that whosoever believes in him and gets baptized and does good works should not perish, but have everlasting life.

The False According to Mormons:

For God so loved the world, that He gave His only begotten Son, that whosoever believes in him and is baptized and does perfect works should not perish, but have everlasting life.

This false teaching requires the works of man to bring about salvation. The thief on the cross was not baptized, nor did he do good works, yet he will be in paradise with Yeshua.

These are just a few of the false teachings being preached that you should be mindful of. If anyone comes to you preaching these false teachings, reject them and embrace only the truth as revealed in John 3:16;

For God (Father YHWH) so loved the world, that He gave His only begotten Son (Yeshua), that whosoever believes in him (Yeshua) should not perish, but have everlasting life. John 3:16
