The future is always unknown. A kind of constant state of change controls the future...or uncertainty. So there is no reason to predefine your future...they only thing you can do is shape your future with today's actions.
As for John 3:16....Do you really believe that God would put stipulations on his love? Really? That goes basically against all the bible teaches about unconditional love does it not? I know, my opinion is biased. I believe in God and Jesus also. I don't believe in the Church or it's interpretation of the bible. Instead I follow the norms and moral values the bible teaches knowing that if I do that everyday....Life will be easier. Which it is.
As for the challenges....They make you stronger and that is the reason they are placed in front of you.
Be strong, be you, and don't let others actions control your future....Start defining who you will become.
