One of the great symbols of change and answered prayer in my lifetime was the end of the Cold War. The East German government agreed on this day that the Berlin wall could come down on this day. This symbol of separation and division. This icon of atheistic communism. This wall that seemed to be of iron came down virtually in a day.
Christians around the world had been praying for years about the Cold War and the collapse of the Berlin Wall ... and then it happened. It was momentous, but the reality is that a whole generation have passed who almost have never heard of communism.
This answered prayer should be something of an "Ebenezer" monument to remind the church that "Till now the LORD has helped us" (1 Samuel 7:12) and to expect great things from the LORD. To walk by faith with godly expectation is the fruit of a truly reformed life. Our doctrine and faith are both to be shaped by a living reality of leaning upon the covenant LORD.
Since the Berlin wall came down, sadly much atheistic materialism from the West has engulfed former communist states. There have been advances in places like Albania and other countries but much mission work is needed. Do you pray for the strengthening and growth of the church in Poland, Former East Germany, the Balkan countries, Romania and so forth. If not, the do so.
Then he said to his disciples, “The harvest is plentiful, but the laborers are few; 38 therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest.” Matthew 9:37-38.
Isaiah prayed also "Here am I send me!" We need Christians and ministers to offer themselves again in large numbers to serve the LORD in our own generation.
