“Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled.”
I am sure you don’t want to fail. Every child should desire to succeed in life. The same goes for our spiritual life. As children of God, we are expected to succeed in living a peaceful and holy life. In the previous verse, Christians were exhorted to “Follow peace with all men, and holiness, without which no man shall see the Lord” (Hebrews 12:14).
If we are to succeed in maintaining godly relationships with one another, first and foremost, we must diligently rely upon God’s grace. A harmonious and holy relationship with one another as God’s children cannot be successfully pursued in our own power. We need to fully depend upon His grace, for only by His grace can we fulfil all our Christian responsibilities to one another and to God. Make sure you rely constantly on the promised grace.
Do always what God graciously commands you to do. Don’t let your own bitter feelings against others corrupt your mind to disobey God’s counsel concerning your relationship with and responses to other believers. If believers are to bear the good fruits of peace and holiness, then they must also shun sins, such as bitterness. Let not unhappy feelings and anger discourage you from relying on God’s grace to follow peace and holiness. Remember to warn yourself always that bitterness of heart will defile you. So, if at any time bitterness starts to develop in your heart, seek diligently, by prayer, God’s grace to subdue all ill feelings and act in a peaceful and holy manner.
