今天經文的主要信息是：上帝活在祂百姓的生命中，祂從世界及其話語中啟示了自己（詩19）：祂賜能力與勝利給為祂爭戰的人（詩20、21）；祂差遣彌賽亞在十字架上代死（詩22）；牧養祂的子民（詩23）；建立祂的權能掌理全地（詩24），是的，祂配得你我的信靠。

        問題：一般來說，退休金、學位和核子潛艇的用處何在？
        答案：他們可以給你安全感，使你對未來感到安全，對假期感到安全，對本身感到安全，但是否真能如願呢？
        在這個日漸動盪不安的世界裡，人們所謂的安全感，往往只是對物質享受的追求。
        大約三千年前，最主要的軍事武器是戰車與戰馬，在戰場上若能開出一隊騎兵或是一列戰車，別人絕對會相信他們是一支攻無不克的勁旅！
        但在以色列卻不是這樣，上帝律法禁止以色列王蓄養大量戰馬（申17：16），卻要他們把信心放在決定一切的膀臂中，以色列只要信靠那永恆的膀臂即可，因為上帝早已應許為他們爭戰到底，這就是為什麼大衛堅信上帝的拯救（詩20：7），同時這也是「國家安全」問題的答案──不論在大衛時代，或是你的時代都是一樣的。
        在一張紙上，用鉛筆寫下五件這個世界可以給你安全感的條件，然後劃掉，再用原子筆寫上詩篇二十篇七節的經文：「有人靠車，有人靠馬，但我們要題到耶和華我們上帝的名。」美國的錢幣鑄著「信靠上帝」四個字，在你的心版上鑄的是什麼字呢？

        提到車馬…
        以色列的安全常常受到敵人戰備精良車隊的威脅，但兩軍衝突的時候，以色列是如何克敵致勝的？請看出埃及記十四章，士師記四章，及列王紀下六章，便見分曉。

他們蒙保守，一如上帝的應許。

        God's involvement in the lives of His people is the dominant theme of the psalms in today's reading. God reveals Himself in the world and in the Word (19); He gives enablement and victory to those who do battle for Him (20-21); He sends His Messiah to suffer on the cross (22), shepherd His people (23), and establish His rule over the earth (24). Indeed, He is worthy to be trusted!

        Question: What do retirement funds, college degrees, and nuclear submarines have in common?         Answer: They are all designed to give you a sense of security: security for your future, security for your vocation, security for your protection. But do they?
        Security in an increasingly insecure world. It's one of today's most sought after—and elusive—commodities.
        Nearly 3000 years ago, the ultimate military weapons were the chariot and the horse. Armies which could field a cavalry or chariot brigade were considered virtually invincible.
        But Israel was to be different. God's law forbade her king to multiply horses (Deuteronomy 17:16). Rather than put her confidence in strategic arms, Israel was to trust in everlasting arms, for God had promised to fight for His people. That is why David's affirmation of trust in a delivering God (Psalm 20:7) is so appropriate. It's the answer to the "national security" problem—both in his day and yours.
        On scratch paper, list in pencil five things the world tells you will make you secure. Then across the list, write in ink the words of Psalm 20:7—"We will remember the name of the LORD our God." America's coins are stamped "In God We Trust." What sentiment is stamped on your heart?

        And Speaking of Chariots .. .
        Israel's security was often threatened by chariot-equipped armies. What was the outcome of the skirmishes described in Exodus 14? Judges 4? 2 Kings 6?

They are well kept whom God keeps.
