上帝是無所不知的。然而，根據華爾街日報的一篇報導，美國國家安全局透過我們的智慧型手機數據，也對我們瞭若指掌。每個擁有手機的人都會產生「詮釋資料」（metadata），留下數位軌跡。雖然每個單獨的零碎數據似乎微不足道，但被整合分析之後，就會變成史上一個最強大的調查工具。透過追蹤這些詮釋資料，調查人員可以精準定位我們去過哪裡，或明確指出某時某刻我們身在某處。

大衛說上帝知道關乎我們的一切，這遠勝於國家安全局的數位軌跡分析。在詩篇139篇，大衛向上帝祈禱，而只有這位上帝能探尋、鑒察我們所有的意念（1節）。大衛寫道：「上帝啊，求祢鑒察我，知道我的心思」（23節）。上帝知曉我們的一切（2-6節），祂無處不在（7-12節），創造我們的肺腑（13-16節）。上帝的意念遠高過人類的理解（17-18節），就連我們面對仇敵的時候，祂都與我們同在（19-22節）。

因為上帝無所不知，無處不在，無所不能，所以祂清楚知道我們去過哪裡，做過什麼，以及我們是怎樣的人。但祂也是一位慈愛的天父，祂會幫助我們遵行祂的道。讓我們今天就跟隨祂走這條生命的道路。

God truly knows all. But according to an article in The Wall Street Journal, the National Security Agency knows a great deal about us as well through our smartphone data trails. Everyone who owns a cell phone creates “metadata” that leaves a “digital trail.” While each individual crumb of data might seem insignificant, when it’s combined and analyzed, it provides “one of the most powerful investigative tools ever devised.” By tracing our metadata, investigators can pinpoint where we’ve been or where we are at any given moment.

Far more superior than the NSA’s digital trail analysis, David said God knows where we are in relation to Him. In Psalm 139, he addresses a prayer to God, the one who alone can search and examine what’s going on inside of us (v. 1). The psalmist wrote, “Search me, God, and know my heart” (v. 23). He knows everything about us (vv. 2-6), is present everywhere (vv. 7-12), and “created [our] inmost being” (vv. 13-16). His thoughts are higher than our human understanding (vv. 17-18), and He’s even with us as we face our enemies (vv. 19-22).  

Because God is all-knowing, ever-present, and all-powerful, He knows exactly where we’ve been, what we’ve been doing, and what we’re made of. But He’s also a loving Father who will help us walk in His ways. Let’s follow Him down the trail of life today.
