How do we know that the Holy Spirit teaches us all things?

The assurance of the Holy Spirit's teaching comes from passages such as 1 John 2:27, where it states that 'the same anointing teacheth you of all things and is truth.' This indicates that the Holy Spirit is not only present but actively guides believers in understanding spiritual truths. Additionally, the Holy Spirit's ministry is echoed in John 16:13, which affirms that He will guide you into all truth. Therefore, believers can trust in the Holy Spirit's ability to reveal and explain God's Word, as He uniquely understands both the mind of God and the hearts of believers.
