In the daily battles of life one can be tempted to give in to depression or fatigue as we see sin and compromise increasing. Yet there is hope. God is sovereign. Nothing is inevitable except what God has decreed. And there is power in prayer.
Christians are not doomed to defeat but called to victory. If God can change us then He can use us to change some part of this world. Christians can change the course of human history by prayer and obedience to God. The Bible is full of examples of believers
"who through faith conquered kingdoms."
And recent history confirms the power of prayer.
Shortly after I was converted to Christ early in 1977, I remember an OMF missionary urging us to pray for God to open the doors to Red CHINA. Evan as we prayed my heart was filled with unbelief - how could a communist country like China ever be open to the Gospel again? Yet we have seen how Mao Tse Tung died, how his little "Red Book" became discredited and how the doors to china have been gradually opening since.
