There can be debris - unhelpful or ungodly attitudes and habits for example - in our lives, which, unattended to can build up and block the flow of God's love within us. We usually know it's there, but may pretend it's not or try to cover it over with activity or other diversions. The problem then, it can fester and spread, causing us to lose our peace and we become restless.
When we humble ourselves, take courage and face these things with Jesus, we find such forgiveness and cleansing that releases freedom and blessing. God's peace returns and we become calm and still inside. Others may even want to draw close and enjoy being with us.
"I live in a high and holy place, but also with him who is contrite and lowly in spirit, to revive the spirit of the lowly and to revive the heart of the contrite. -- I have seen his ways, but I will heal him; I will guide him and restore comfort to him -- But the wicked are like the tossing sea, which cannot rest, whose waves cast up mire and mud." Isaiah 57:15-20 New International Version
