What does it mean that God is able to make you stand?

Romans 14:4 states, 'Who art thou that judgest another man's servant? To his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.' This promise assures us that each believer is accountable to God, who is fully capable of supporting and maintaining our spiritual standing. God provides the grace we need, empowering us to live out our faith amidst our struggles, thereby encouraging us to accept one another in love, regardless of our individual differences or spiritual maturity.
