Desire to be our own Lord a. Broken relationship with God b. Broken relationship with one another c. We need something or someone to restore us to God. There is a sin problem separating us from God and we need that repaired somehow. Redemption is one name for the solution. It means literally to be bought back - and be in a right relationship again.
Restoration is a word describing the relational process.
Yet, what we discover is that we cannot effect our own healing. It is Jesus Christ that brings our healing. First we have a word about the name - Jesus Christ. Jesus is a common name - but its root is Savior. It is from a Joshua root.
