Why is it important for Christians to examine their hearts?

For Christians, examining our hearts is a vital practice that reveals the true state of our faith and understanding. The interplay between our affections and beliefs speaks to the authenticity of our relationship with God. If our hearts, which encompass our desires and feelings, are unchanged, it may suggest that we do not fully grasp or believe the Gospel. Thus, this inward examination helps foster a genuine response to grace, resulting in the production of spiritual fruit such as love, joy, and gentleness in our lives.
