God deplored the insincere faith of Ephraim and Judah: “O Ephraim, what shall I do to you? O Judah, what shall I do to you? For your faithfulness is like a morning cloud, and like the early dew it goes away” (Hosea 6:4). He still does. In defense of His interaction “with tax collectors and sinners,” Jesus explained that He came to call sinners to repentance – those who need spiritual healing (Matt. 9:11, 13). He applied Hosea to His critics, “But go and learn what this means, ‘I desire mercy and not sacrifice’” (Matt. 9:12). Accurate knowledge of God compels mercy toward sinners without forgetting one’s dutiful offerings to God (Matt. 23:23; Psa. 85:10-13). We have received His mercy and are to be merciful as we serve God (Matt. 18:33). Yet, being a Christian is often reduced to rituals and formalities in not a few churches. Sinful conduct of members is winked at and ignored because they are large donors, prominent in the community, in regular attendance at worship services, or otherwise highly regarded (1 Cor. 5:1-2). They may “fast twice a week” and “give tithes of all” they possess, but such things are meaningless to the Lord when hearts are far from Him (Lk. 18:10-14). God foretold and executed judgment upon Ephraim and Judah for their insincere, disobedient faith (Hosea 6:5). Let us learn from their failures and not repeat their sins (1 Cor. 10:5-13). Genuine and enduring faith must be driven by mercy toward others as we keep the commands of God.
