Read Romans 16:25-27
25 Let us give glory to God! He is able to make you stand firm in your faith, according to the Good News I preach about Jesus Christ and according to the revelation of the secret truth which was hidden for long ages in the past. 26Now, however, that truth has been brought out into the open through the writings of the prophets; and by the command of the eternal God it is made known to all nations, so that all may believe and obey.
27 To the only God, who alone is all-wise, be glory through Jesus Christ for ever! Amen.w
The Good News about Jesus Christ - truth brought out into the open - that was hidden in ages past.
Jesus is the final word about God... in Jesus what was once hidden is revealed; God's person - his word to the world.
Jesus don't let me become so familiar with you that I forget the mystery you reveal. God. Powerful and holy. Loving and just. Help me to see you - and worship you.
