A brief but edifying account of G.I. Willimason's ministry can be found here.
Ministry wisdom from the man himself, undoubtedly utilized by him all these years and ignored to a pastor's detriment, follows:
The eschatological is:
1. Eternal reality of the kingdom paradise promised to Adam in the CoW.
2. Immutable state of perfect life in the presence of God.
3. Heavenly goal of the promised kingdom under the CoW.
4. The final stage of the kingdom of God, the telos point, the omega point.
Summary: The eschatological is the eternal, immutable, heavenly, and final state of the kingdom of God.
