The law of the Lord is perfect and trustworthy, reviving the soul

Psalm 19:1-14
The glory of God is fill whole universal, God's word is the knowledge which is abundant and could not explained day after day and night after night.
God word has power and nothing is hidden from it heat.
The law of the Lord is perfect, reviving the soul. The statutes of the Lord are trustworthy, making joy to the heart. They are more precious than gold, sweeter than honey. By them is your servant warned; in keeping them there is great reward.
Who can discern his errors? Forgive my hidden faults. Keep your servant also from willful sins; may they not rule over me.
May the words of my mouth and the mediation of my heart be pleasing in your sight.
God's universe describes his glory in speech without words.
The psalmist's thought leaps straight from the sun, with its all-pervading, searching rays, to the law of God - pure and clean, bringing joy and wisdom, instruction and enlightenment to our hearts; and to his own need of protection and cleansing from sin.
Why?
Man usually can not discern our errors and sins. Pray to the Lord keep me from willful sins and may they not rule over me.
Keep clean mouth and heart is an important, which needs God's blessing and our heart focus on God.
How?
No matter what happen to me, God is trustworthy. May the words of my mouth and the mediation of my heart be pleasing in God's sight.
