In order to benefit others...

Let our love be only in Christ.  In order to benefit others you must live in the love of God, otherwise you are unable to do good to your fellow man.  You mustn't pressurize the other person.   His time will come as long as you pray for him.  With silence, tolerance and above all by prayer, we benefit others in a mystical way.  The grace of God clears the horizon of his mind and assures him of His love.  Here is the fine point.  As soon as he accepts that God is love, then abundant light such as he has never seen will come upon him.  Thus, he will find salvation.
