Silence and Smile

One psychologist explained that life could be better if people adapt two simple principles: Silence and Smile. In fact, people who are wise, mature, righteous, and humble use these, even when they are provoked.
Wisdom: Sometimes, even fools are considered wise, when they keep silent and prudent when they close their lips. (Proverbs 17:28) God’s greatest gift to humans is the skill to think and express the thoughts in words. Nevertheless, words could create blessings as well as cursing or encouragement as well as discouragement, affirmation as well as rejection. Silence is preferred over hurtful, cursing, demeaning and hateful words. When a disciple is unable to speak good words, it is better to keep silent.
Model of Lord Jesus: First, Lord Jesus loved people, especially the rich young, he probably expressed in His smile. (Mark 10:21) Second, Peter, probably witnessing Lord Jesus from close quarters after his arrest writes: When Lord was insulted, he did not retaliate, he suffered without threatening. (I Peter 2:23) Third, Prophet Isaiah writes that Lord Jesus would be silent like a sheep taken by shearers. (Isaiah 53:7) Four, there was no deceit found in his mouth. (Isaiah 53:9)
Silence in Holy presence: The sons of Aaron, Nadab and Abihu brought strange or profane fire in the censer and offered incense. It was disregard for God’s command or utter foolishness. God’s wrath came upon them, they fell dead. Aaron was shocked and stunned. Moses explained that those who come near the Lord must understand God is Holy and He will be glorified before all people. The two sons violated God’s expectations. Aaron was silent. His right to grieve for his sons must be sacrificed for the sake of God’s Holy presence. (Leviticus 10:1-3) In God’s Holy presence, the world should be silent. (Habakkuk 2:20)
Blessed woman: Smile is a friendly expression of face. The Blessed wise woman smiles at the future. (Proverbs 31:5) Wise woman was not afraid about the future, as she was confident about the future. For she had diligently, wisely prepared for the future.
