Every Christian a missionary; every non-Christian a mission-field.
God has guarded His Word so that only the pure in heart can see its secrets. All other efforts will fail.
No matter how high the powers of reason, no matter how deep the intellect, no one can discover God's secret messages without paying the cost of true discipleship.
God can use the jawbone of an ass!
Faith is a record of great risks taken.
Many do not recognize the call of God simply because they have never taken the time to really talk with Him long enough to know what He is like.
