What does the Bible say about spiritual laziness?

Spiritual laziness is highlighted in the sermon through the interpretation of Song of Solomon 5:2-8. The preacher discusses how even true believers can fall into states of coldness and indifference towards their relationship with God. This is not a reflection of spiritual death but rather a neglect of their spiritual duties. The Apostle Paul sheds light on this struggle in Romans 7, where he expresses the internal conflict between the sinful nature and the spiritual desire to serve God. Believers, despite being saved by grace, often find themselves caught up in excuses for not responding to God's call, encapsulated in the metaphor of 'sleeping' while their hearts should be awake.
