God’s plan for a purpose of love IS based on a plan – which God wisely developed, and detailed right from the start.
8 “Remember this, and be assured;
Recall it to mind, you transgressors.
9 “Remember the former things long past,
For I am God, and there is no other;
I am God, and there is no one like Me,
10 Declaring the end from the beginning,
And from ancient times things which have not been done,
Saying, ‘My purpose will be established,
And I will accomplish all My good pleasure’;
The only way that God could “declare the end”, “from the beginning””in ancient times” (an understatement for eternity past), would be to work out right from the start all of the details of His plan, and be able to guarantee the execution of each of those details. Any other way would cause the plan to veer off course. Think about some of your own plans that you made in your life – they never worked out exactly as planned because there were always details that you were simply not able to control. This did not happen with God’s plan. He wisely planned all of the details and controlled them, so that He could declare right at the start what would be the outcome of His plan – the fullest expression of His nature (love, justice, etc) and strength.
