We should do two things when understanding time. See what the Scriptures state or imply, and then use our God-given faculty of reason to apply the most logical explanation.
Psa 106:48 Blessed [be] the LORD God of Israel from everlasting to everlasting: and let all the people say, Amen. Praise ye the LORD.
Psa 90:2 Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou [art] God
Psa 41:13 Blessed [be] the LORD God of Israel from everlasting, and to everlasting. Amen, and Amen.
The above verses I posted suggest something which, if you think of God as eternally residing IN TIME become absurd. The phrase "everlasting to everlasting" is nonsense if we take it to mean a continuous series of events such as our present reality. If time is infinite....then we do not exist....because this present moment in time has yet to occur.
1.) If time is infinite/had no beginning the present moment would not have arrived
2.) The present moment has arrived
3.) Therefore time had a beginning
4.) Therefore the phrase "from everlasting to everlasting" is not speaking about infinite succession of events.
5.) Actual infinities do not exist
Remember Leibniz: "Why did God wait so long to create the Universe"
1Jo 2:17 And the world passeth away, and the lust thereof: but he that doeth the will of God abideth for ever.
1Jo 2:18 Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.
"The last time", suggests that there have been prior "times" and there will be a Last "time". vs. 17 however, seems to stand in distinction from the notion of existing In time, but in a more timeless state called "forever". See below:
Rev 10:6 And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that there should be time no longer:
Once upon a time, there was a time when there was no time :laugh:
More seriously, what this tells us is that time will cease to exist.
2Pe 3:8 But, beloved, be not ignorant of this one thing, that one day [is] with the Lord as a thousand years, and a thousand years as one day.
Easily accomplished by a being for whom time is essentially meaningless, and who is in no way constrained by time.
Conclusion: He Created time, Time will end.
With respect to A and B series: Craig's belief is that the A series time is the only real "time" and that B series is pablum. That God existed (prior to creation) timelessly and that he has inhabited time (A series) for the moment and will cause time to cease to exist....wherein we will be with him forever...timelessly.
