Hopelessness can lead to a troubled heart (uncertain is the translation from Greek) laziness, depression and even premature death.
The Believers hope is not based on wishful thinking but our hope is resting on the Resurrection of Jesus.
Hope is an Anchor for our Soul to keep us steady in troubled waters.
When Jesus rose he made good on his prophetic promises.
The resurrection solidifies our Salvation, Defeats the Devil, Hell and the Grave.
Hope is confident assurance and certain expectation.
