Esther 9 speaks of days of feasting and joy (Esther 9:17-19,22-23,28). If the Jews had cause to rejoice in Esther’s day, we have much more cause for rejoicing in the Lord – “Do not weep! See, the Lion of the tribe of Judah, the Root of David, has triumphed” (Revelation 5:5). The praise of God’s people does not arise only from the Jewish nation. It comes from “every tribe and language and people and nation” (Revelation 5:9. Our rejoicing is in Jesus Christ, “the Lamb of God”: “Worthy is the Lamb, who was slain, to receive power and wealth and wisdom and strength and honour and glory and praise!” (Revelation 5:12). This praise will continue throughout eternity: “To Him who sits on the throne and to the Lamb be praise and honour and glory and power, for ever and ever!” (Revelation 5:13). Proverbs 30:18 speaks of things that are “too amazing” for us, things that we “do not understand.” This is the Gospel. It stretches far beyond our understanding. Through amazing grace, such great things have been revealed to us. This is why praise arises in the hearts of God’s people as a song which will continue for all eternity.
