You have yet to answer my question why is God under obligation to die for us?
"You have yet to answer my question why is God under obligation to die for us?"
John 3:16, "And this is the way God loved the world, He gave His only Son to die for us...".
God is only under obligation IF He wanted to save some. God's justice, or nature, or essence (you get the idea :) demanded that a price be paid for man's sin in order for any to enter Heaven. Heaven is definitionally unfit for sinners, per se. Man checked his pockets and came up FAR short of the cost. Now the only choices are that God let all perish in hell (perfectly just), OR that God pay the price Himself out of His love for His elect (also perfectly just). God obviously freely chose the latter to get what He wanted, while at the same time being true to His own nature. God MUST be true to Himself, AND He had a desire. The only way to satisfy both was by our Lord Jesus becoming a sacrifice.
