God is ever present, so you may speak to him or hear him speak to you at any time. Seeing it this way, we have plenty of time. On the other hand, life is brief and it's easy to go through life without ever thinking about God. Looking at it thus, we don't have much time at all. It comes down to this: those who care about God will find and know him and those who do not, will miss and lose him entirely. As Jesus said, "To the one who has, more will be given; from the one who has not, even what he has will be taken away."
