God calls us to align our hearts with His purpose and objective, not our own. To be ready for God's inspection, we must approach it with His priorities in mind. The sermon emphasizes the importance of confession and having a clear heart before God. The speaker encourages listeners to regularly examine their hearts, confess their sins, and consecrate themselves to God's service. For inspection readiness, we should present ourselves according to God's standards, not our own, with clean hands and a clear heart.
