Being one who "made a decision" for Jesus, but was then truly saved by the grace of God alone, I share this video in hopes it may open eyes to the error of this practice. This article by James Adams goes into more depth. Modern evangelism owes more to heretic Charles Finney than it does to godly preachers from years past like Spurgeon, Whitfield, and Edwards.
Modern evangelism and it's emphasis on "me" is a far cry from historic orthodox christianity and it's emphasis on faith alone, grace alone, and Christ alone. We are wicked sinners who have nothing to offer God, but instead can do nothing but cast ourselves on Christ for mercy. Try preaching that in the average seeker sensitive church.
