I think so to. In studying the OT, we can at times see almost two different descriptions or revelations of God. In the Gospel we see which is more accurate - dramatically so in the Incarnation.
John 3:16 without quoting the whole context of the verses
The latter does not contradict what came before it. It says "Whoever believes," not double predestination.
Is this what you believe??? That the NT is more accurate than the OT???
The scriptures are all written by God through the prophets, completely accurate and error free. One section isn't more or less accurate. It all paints a picture of God, the nature of God, and God's interaction with man. In fact, our Lord Jesus quoted from the OT extensively, including Noah, Jonah, and others.
