Free decision

“Do you think I cannot call on my Father, and he will at once put at my disposal more than twelve legions of angels?  But how then would the Scriptures be fulfilled that say it must happen in this way?”   Matthew 26:53- 54

There are no ifs, ands or buts about our salvation.  Yet here the Lord reveals to his disciples that their salvation, though predestined from before the foundation of the world, is nevertheless based on His own voluntary, free decision.
