Now as to why the tree is forbidden. First the tree is just conscience, it helps you the difference between good and evil. In fact, God used the Tree to test the first Man and Woman to see if they truly love and obey Him. And we must know that obeying him is just for our own good cos when we are faced with the real situations in life (the good and bad of life) we might not be that strong.
Secondly, why is it forbidden?…..u must know that; life and relationship without true test is fake. The yard stick that makes you know how devoted you are is how good you can fight temptation. Life is good when you are given good odds, but is sucks cos you wont know how good are really doing, but when there is temptation and you still stay faithful , then you can say Yes…I Think Am Doing Good. God wanted to know if the first human really loved him…and I guess he was disappointed. Which is why it’s up to us to make things right. Our today, my today, your today is his second chance. Don’t blow it.
