Isaiah 26 : 1-6 / Matthew 7 : 21, 24-27
The Berlin Wall was built in 1961 to separate the communist East Germany from West Germany.
Along with that wall were electrified fences, mine-fields, guard-posts and at regular intervals, tall towers with search lights.
It was a formidable sight, and all this just to protect a Communist political system, and also at the expense of lives who tried to escape from that system.
Yet in 1990, the Berlin Wall crumbled. It crumbled from the people's urge for freedom from an oppressive system.
But as we look deeper at it, the Berlin Wall crumbled from the power of God's will to grant freedom and peace and unity among peoples.
The prophet Isaiah urged his people to trust in the power of God rather than in steep citadels and fortifications which will eventually crumble.
Because high walls and electric fences will not protect us if our hearts are not with God.
Real defense against fear and insecurity and evil is having a faithful heart which will trust in the Lord.
When we put our faith in God and build our lives on the Lord who is the Everlasting Rock, we will not crumble in the face of evil and suffering and oppression.
