The concept of “blessing” in Scripture either means, “to be happy” or, “to speak well of”. To eulogize someone is to bless them by speaking well of them; speaking of the good things someone has done.
Eulogy is often used concerning God and His Christ. When we “bless” God, we are speaking well of Him due to His character and what He has done. He visited and redeemed His people (Luke 1:68). He is the Father of mercies and comfort (2 Corinthians 1:3). We are born again according to His mercy through the resurrection of Jesus Christ out from the dead (1 Peter 1:3). Christ was first sent to the Jews to speak well of them by turning each one of them away from their malignant evil (Acts 3:26).
In a world that loves darkness (John 3:19), we walk as luminaries by showing the life of God in action (Philippians 2:15); therefore, in contrast to those who blasphemy and revile us, we are to speak well of them (1 Peter 3:9), seasoning our words with a bit of grace (Ephesians 4:29; Colossians 4:6), for remember, it is the kindness of God that brings a change of mind, not wrath (Romans 2:4). This is not ignoring someone’s wrong or overlooking the necessity of penalty for their actions. It is to not retaliate in kind. They persecute, blasphemy, and revile us for living and speaking the truth, but we do not speak things about them that are not true nor curse them (Romans 12:14), for they will be put to shame in the day of visitation, when others examine us and see our works are good (1 Peter 2:12). And as we mature in Christ, let us learn to control our tongue so that we are not using it to curse men while speaking well of God (James 3:9).
In Communion, the cup that we speak well of and the bread that we break in remembrance of our Lord, (1 Corinthians 10:16) is because the cup represents the new covenant (1 Corinthians 11:25; Hebrews 8:6) and the bread the body of The Christ (1 Corinthians 11:24). One who eats and drinks in an unworthy manner, not discerning the body of the Christ, drinks judgment upon himself, for this is not something to take lightly of, or we would not speak well of it (1 Corinthians 11:29-32).
When it comes to the Christian, God speaks well of us in the heavenlies concerning spiritual things (Ephesians 1:3). God has given us all things pertaining to life and godliness (2 Peter 1:3). Satan accuses us (Revelation 12:10), but God speaks well of us, for we are righteous ones in Christ (1 Corinthians 1:30). And as ones of faith, we are well spoken of just as Abraham (Galatians 3:9).
Since God speaks well of us concerning Spiritual things, let us live a life that manifests His opinion of us, lining up with what He says, for He always speaks the truth.
