Isaiah 26:3-4: Despite What You Tell Yourself

Isaiah 26:3-4: You keep him in perfect peace
whose mind is stayed on you,
because he trusts in you.
Trust in the Lord forever,
for the Lord God is an everlasting rock. [1]

Have you heard the expression: “I am my own worst enemy?” At times are you bothered by your own thoughts? If you are a believer in Jesus Christ, do you wrestle with assurance of salvation? If you can say, “yes” to any of these questions, you need these verses for yourself and/or your friend(s). Isaiah teaches that God’s faithfulness sustains and enables Christian faith. [2] Because the LORD is changeless (regardless of people) and faithful, [3] He generates, [4] guides, [5] and energizes faith. [6] By God-given and enduring faith Christians can wrestle with their doubts, the lies Satan and the world whisper in their ears, and live a thriving life for their Savior Jesus. [7] Regardless of what we tell ourselves.

Isaiah is also clear that the Trinity’s peace is exclusively for those who exclusively follow Christ. [8] If you desire help with the sorrow in your heart, work’s crushing weight, family woes, etc. you have that if you admit your guilt to the Triune God and strive to be His by His Holy Spirit. [9] These promises are true, attested, and good despite what you have heard and tell yourself. [10] Come to Him, and Jesus Christ will be your rock. [11]
