A Word to My Evangelism Brethren

Here in rainy Ohio, we are ready to get back into our "nice weather," which means an increase in our outreach efforts.  This is an exciting time.  But with that, I again pass on the burden of my heart.  We can be very zealous in evangelism.  In fact, many of us travel great distances and make personal sacrifices of money, time, and energy to be a part of an outreach event.  My question for myself and others is this - to what degree do we sacrifice to take part in a time of prayer with other believers?  Let us not "hit the streets" this summer in the floesh, but may we go forth in the power of the Holy Spirit.  May we be as fervent in prayer as we are in evangelism.
