An old Protestant hymn, "Almost Persuaded," is a kind of hard-sell altar call that incorporates two common lies (eternal security, and today as the only day of salvation). The adjective "almost" in Acts 26:28 distorts the correct meaning. The terms "almost" and "altogether" refer to periods of time (suggesting different periods of salvation) rather than insufficient or puny proofs. God can bring about salvation on His own timetable rather than as a kind of used car salesman's "now or never" pitch suggested by the Protestant hymn.
