Then that would not really be predestination in the Biblical sense, since it would depend upon something we do. It would make salvation be something we have earned.
What you are not understanding, is outward works do not produce eternal life, they are not accepted by God as a pure sacrifice. But in Romans, this is what it does say, that we are called to do, in order to please God. Inward works.
Romans 12:1-2
1 Therefore, I urge you, brothers and sisters, in view of Gods mercy, to offer your bodies as a living sacrifice, holy and pleasing to Godthis is your true and proper worship. 2 Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what Gods will ishis good, pleasing and perfect will.
In other words if we don't so this, then we are not pleasing God. Since it says offering our bodies to Him as a living sacrifice, is what pleases Him. Notice it says, "in view of God mercy", we are told to do this, with the view that His mercy depends on us offering our bodies to Him in this way.
Now look at this verse....
1 Timothy 4:16
Watch your life and doctrine closely. Persevere in them, because
if you do, you will save both yourself and your hearers.
IF we watch our life and doctrine closely, we will save ourselves? And our hearers? How can you get around these verses, that God calls you to live this kind of life, in the person of Christ, which produces eternal life?
What about this verse?
Luke 9:23-24
23 Then He said to them all, If anyone desires to come after Me, let him
deny himself, and take up his cross daily, and follow Me. 24 For whoever desires to save his life will lose it, but whoever loses his life for My sake will save it.
We aren't following Christ, if we are not obeying what He preached. He said, we must deny ourselves, take up our cross DAILY, and follow Him. This is what Christ said Himself. We are commanded, to walk by the Spirit, by the new man, rather than our sinful nature. We must do these things, with the power of the Spirit, or else we are not obeying God, and ultimately not walking in His love, according to the word of God.
