A standard definition of hope is "to feel that something desired may happen". 'Feel' and 'May' are the words that denote uncertainty. These are the two most important links which connects you to that unseen supernatural power and inspire confidence to connect with God. Hope might not hold the promise of security, but paradoxically, it enhances our capacity to live, work and ultimately transform ourselves within an insecure, unstable environment.
Most of us hold on hope against all odds. And hope creates/germinates the linkage of trust with God.
