Zeal

An earnest temper; may be enlightened (Num 25:11–13; 2 Cor 7:11; 2 Cor 9:2), or ignorant and misdirected (Rom 10:2; Phil 3:6). As a Christian grace, it must be grounded on right principles and directed to right ends (Gal 4:18). It is sometimes ascribed to God (2 Kgs 19:31; Isa 9:7; Isa 37:32; Ezek 5:13).
