Having Assurance Before God

The book of 1 John was written to strengthen believers in their holy faith. It was written to give them the assurance that they belong to God as his beloved children, in spite of their struggle with their own sin. This passage gives believers four grounds or reasons that they can have assurance that they really are saved from their sins and are secure in God. It's because of their "deed-doing," their "truth-keeping," their "love-giving", and their "Holy Spirit-abiding." In other words, the ongoing presence of good works in their lives, their belief in and fidelity to the truths of the Gospel in the Word of God, their sacrificial love for fellow believers, and their continual abiding in the presence and fellowship of the Holy Spirit are marks, evidences, that they possess true and saving faith. When they feel condemned for their sins, they can look at these realities in their lives and rest in the assurance that God has saved them and is working in their lives.
