Spiritual changing vs. the law changing
Jesus and Nicodemus were both great teachers.
Jesus emphasized the spiritual inner of a person’s changing process, and Nicodemus dealt with observing the religious law. The process is being born again in spirit and water that you keep the law but not the other way (John 3:1-18, NIV).
Moses put a bronze snake on a pole to save people from dying of snake bites in the wilderness. Some people refused to follow the instructions, and they died of snake bites (Numbers 21:4-9). A born-again person in water and spirit, the inner self-state is changed, leading to desires constantly doing good things unsupervised. And fulfills God’s command and purpose sated below:
Then God said, “Let us make mankind in our image, in our likeness, so that they may rule over the fish in the sea and the birds in the sky, over the livestock and all the wild animals, and over all the creatures that move along the ground.” 27 So God created mankind in his own image, in the image of God he created them; male and female he created them.
God blessed them and said to them, Be fruitful and increase in number; fill the earth and subdue it. Rule over the fish in the sea and the birds in the sky and over every living creature that moves on the ground (Genesis 1:26-28, NIV).
My take way. It took me a long time to realize that God blessed me before I was born, put me in his riches in the earth, and I commanded me what to do in my life to live a glorious life.
