How do we know God teaches us the truth?

The sermon emphasizes that the assurance of knowing the truth hinges on God's revelation through scripture. In Isaiah 54:13, it states, 'They shall be taught of God,' affirming that true understanding is given by Him. Similarly, Romans 10:17 articulates that faith comes by hearing the word of God. Thus, the believer's confidence is rooted not in human reasoning but in divine instruction, affirming the historic Reformed understanding that God is the ultimate source of truth, not man. This teaches us that genuine faith arises from God's Word, rather than from our efforts to understand or prove it.
