2 Kings 5:1-27 reveals that the Lord’s grace is both awesome and terrifying. Awesome in that the Lord saves such undeserving sinners in His merciful kindness; terrifying in that the Lord is jealousy severe for the glory of His Name when His grace is scorned. Mr. Brandt Barnard preaches on this in two points: The Lord’s Merciful Kindness and The Lord’s Jealous Severity.
“For Jews demand signs and Greeks seek wisdom, but we preach Christ crucified, a stumbling block to Jews and folly to gentiles, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God.” (1 Cor. 1:22-24)
