I do not make "the difference" in any proclamation of Jesus. Only God can make the difference. The difference made, may be God's direct purpose to harden the mind and heart in the listener.
God doesn't need my help.
Do not be so fretful in laboring to "make a difference, be heard, and be validated" whether among the lost or among the sheep. Such fretting makes an idol of your labor and your impact; Rather be focused on loving God, trusting God, praising God, seeking God, knowing God, and honoring God in the prizing of Jesus: the Prophet, Priest, King, Messiah, Savior, Lord, and Risen Lamb;
In these things it will be impossible for you to be silent before mankind, just as children shout upon seeing newly revealed candy. Thus others will certainly hear of your thankfulness to God in Jesus, by the sheer fact you are amazed with Christ; Their response to your heaven-ward gaze and heaven-ward joy is irrelevant and never a basis for that joy itself. (Just as the kids joy is always for the candy, not the reactions of the adults in the room who may ignore that candy and shout itself).
Yes you will rejoice if souls are drawn to Christ, but you will also rejoice when Christ is victorious and vindicated over His foes. David gloried over Goliath, and John presents a greater glory in Revelation.
