Worship is the vehicle that is at the centre of God and it should be at the centre of our lives also.
God doesn't want men standing before Him and worshipping Him but carrying unforgiven sin and unforgiveness full in our lives.
The bible tells us that God hates the sin in man, God doesn't hate the men and when we touch God with our worship He inturns touches us with love as well but if we are to exalt him the bible tells us to do it with clean hands and a pure heart.
The bible speaks of a man who comes to sacrifice and realizes that he wronged his brother and Jesus says leave your offering by the altar, go back and reconcile with your brother.
God doesn't want man to stand and sacrifice to Him with sin and unforgiveness in our lives.
David in 2 Samuel 11 found it difficult to worship God with the sin of Bathsheba lingering in his life and as soon as he decided offer a guilt sacrifice and dealt with his sin as soon as he finished, worship just bubbled from his heart because he had let it go.
Sin clothes your heart with dirt and God can't look at the sin though he loves the worshipper.
Even though David is the worst sinner in the world bible a title I have given him but God still saw him as the man after his won heart.
The heart of God is that we dust ourselves always and make sure that we don't walk in sin and unforgiveness, live our lives for him.
Worshipping with unforgiven sin and unforgiveness in our hearts will not bring us to enjoy God and his presence.
Hide not thy face far from me; put not thy servant away in anger: thou hast been my help; leave me not, neither forsake me, O God of my salvation.
Psalms 27:9 David believed that God's face was at times hidden from him and I pray that God's face may it continually be shinning upon us always and every day.
Sin will come and when we fall may we rise up, deal with it so that we may continually live in his presence beholding his face.
We should worship God with clean hands, a pure heart, and consecrated spirit, sanctified, sin washed and forgiven hearts because that kind of worship is acceptable.
"Surely the upright shall dwell in thy presence", Psalms 140:13 and "he who walks in the way that is blameless shall minister (worship) to me".
Psalms 15:2 Worship Him In The Beauty Of His Holiness.
