"Hope” is something far greater, more profound, more strongly felt, more firmly based than just expectancy from vague desire. It is more than a wish as it requires you to secure a promise from God. It requires you to be at rest - secure in the knowledge the Lord has promised you a glorious resurrection. It is waiting for the time of the Lord’s promise to be fulfilled. It describes the state of mind of the recipient during the time interval after the promise, but before its realization. It involves unshakable faith or confidence. It is a concrete assurance, based upon a promise or covenant. It comes from knowing the Lord has promised a person something. As sure as God’s word cannot fail, your hope is secure in Him. But you must obtain that hope from Him, by getting him to make a promise to you.
"Charity" is a gift from God, which allows you to love others unconditionally. When resting secure in your own future state, you can love and hope for others in a way you could not if you still worry about your own eternal welfare. Happiness comes from having charity for others. "Charity" comes as those holding real faith and receiving real hope seek to have all others share in the same promises. Concern for the salvation of others lies at the foundation of "charity". The greatest gift you can give to another is eternal life. All those who have such a promise from God want everyone else to have a similar promise for themselves. They teach, preach, exhort and write to share with everyone else that same opportunity. They understand how rare a thing it is to bring a soul to salvation.
"Fear" is always negative. It is the absence of faith and is one of the emotions of hell. For those who are unprepared, "fear" will be their primary emotion on the Day of Judgment. Fear haunts the conscience of those who know they have sinned. Fear keeps one from finding and searching for truth.
