J.C. Ryle on the Effects of Evangelism

"Do you want to understand what the times require of all Christians in reference to the souls of others?  Listen, and I will tell you.  You live in times of great liberty and abounding opportunities of doing good.  Never were there so many open doors of usefulness, so many fields white to the harvest.  Mind that you use those open doors, and try to reap those fields.  Try to do a little good before you die.  Strive to be useful.  Determine that by God's help you will leave the world a better world in the day of your burial than it was in the day you were born.  Remember the souls of relatives, friends and companions; remember that God often works by weak instruments, and try with holy ingenuity to lead them to Christ.  The time is short, the sand is running out of the glass of this old world; then redeem the time, and endeavor not to go to heaven alone.  No doubt you cannot command success.  It is not certain that your efforts to do good will always do good to others but it is quite certain that they will always do good to yourself.  Exercise, exercise, is one grand secret of health, both for body and soul. 'He that waters shall be watered himself' (Prov. 11:25).  It is a deep and golden saying of our Master's, but seldom understood in its full meaning, 'It is more blessed to give than to receive' (Acts 20:35)" (Holiness, J.C. Ryle).
