No, I do not hold to the Calvinist position
God has perfect foreknowledge. Always has had perfect foreknowledge. Because of this, our election and salvation was never undetermined with Him. He has always known us. And He has blessed us with every spiritual blessings. These blessings are in Christ and His Grace to us is in Christ. And when we believe, we are placed in Christ. But Ephesians 1:4 is not about when we believed. It is talking about something that took place before the earth was made.
So if as you say based on God's fore knowledge ,and that ' our ' el,ection and salvation was never ' undetermined ' with him. ( i assume you don't mean ' determined BY him )
Ok then because of this foreknowledge he ' knows ' us . ( both before and in him?) ok this is where it gets slippery
So according to this foreknowledge he blesses us with all spiritual blessings in Christ Jesus , before christ is even christ , before the fall before we were born, before we sinned .
OK then you say ' and when we believed ( I assume unlike determinism where irresistible grace would come in here , you just mean we just freely believe the Gospel by Faith ? ) Then we are placed in christ .
You then say ephesians 1 .4 its not WHEN we believed , but that its something that took place before the earth was made .
OK lots of questions here. But the biggest is , what took place before the earth was made , if it was just in God's mind and you don't believe God determined it ?
