Que sera, sera (whatever will be, will be) i.e. if something is destined to happen, no one can stop it from happening. Yes! it's a matter of time and no matter how unimaginable, unrealizable or unattainable it seems to you or anyone else. For instance, Goodluck Jonathan of Nigeria and Barack Obama of Kenya/U.S.A became presidents against the expectation and imagination of the world. Just because, God is too faithful and well able to begin and actualize whatever he has predestined to do or be. And so, he (God) will surely and eventually bring to pass whatever he has predestined to happen in your life or lifetime. I mean, he will surely make you the person you are destined to be or become. You (can) bet your bottom dollar i.e. it is bound to happen.
