Now may our Lord Jesus Christ Himself and God our Father, who by grace has loved us and given us eternal comfort and good hope, — 2 Thessalonians 2:16

Paul calls God our Father and Christ our Lord the source of everlasting consolation and good hope through grace. This isn't a temporary comfort that fades when hard times hit. By one offering He has perfected forever those who are sanctified. The gifts and calling of God are irrevocable. For here we have no continuing city, but we seek one to come.
