Why is it important for Christians to avoid relying on religious practices?

Christians are cautioned against placing their trust in religious rituals and practices, as seen in the example of those who returned from Babylon. They sought to continue their practices from captivity without understanding that true worship is about heart engagement with God, not mere forms. The Lord, through Zechariah, asks whether their fasting was genuinely aimed at Him. Without seeking to align our worship and practices with God’s revelation and the gospel, we can fall into the trap of self-righteousness, believing that our actions can secure God's favor. True acceptance and worship spring from faith in Christ alone, who fulfills all righteousness on our behalf.
