This concept is “free” according to a Texas-based branch of theology that is the main opposition to the idea of lordship salvation. The singer asks God to “tune my heart to sing” this concept in the hymn “Come Thou Fount of Every Blessing.” The “I” in the Calvinist acronym TULIP stands for a form of this (15[1])concept that overcomes any reluctance among the elect and is therefore “irresistible.” After surviving a storm, a (*) slave ship sailor converted and wrote that this concept “taught my heart to fear” and “my fears relieved.” “Come (10[1])Lord Jesus, our (10[1])guest to be” and “Bless us, O Lord, and these Thy gifts” are examples of a prayer named for this (-5[1])concept said before meals. For 10 points, name this gift of divine salvation that a John Newton hymn calls “Amazing.” (10[1])■END■
