Psalm 37:24 - "Though he fall , he shall not be utterly cast down: for the LORD upholdeth him with his hand." The righteous person is not perfect. Sometimes the righteous fall but when that happens, God is there to forgive and pick the rigteous person up. God upholds the righteous. This means that we are in His hands. Should we fall into sin we fal into God's Grace. If we repent & turn from that sin, He will forgive.
