If our hearts aren't right with God, our worship isn't right either; He won't receive it.
John 4: 23, 24
"But a time is coming and has now come when the true worshipers will worship the Father in spirit and in truth, for the Father is seeking such as these to worship Him.
God is Spirit, and His worshipers must worship Him in spirit and in truth.”
In spirit: breath
In truth: Divine Reality, Verity, the opposite of illusion
Therefore, with every breath we worship and praise and thank God in Truth, in certainty that He Is GOD and there is none other. Thanking Him for our salvation through the blood of His Lamb, His Son Jesus Christ.
Praising Him for His tender, endless mercies.
Worshiping Him for the grace He has extended to us, for the Love He bestows on us.
If our hearts are not right with God, we must repent of our disobedience to His Word that we might receive His pardon on our sins. We must come to the throne of Grace with all humility and humbleness of heart.
Neither pride, nor arrogance will enter God's court. We must surrender our hearts to His. We must choose to submit our will to His will. We must or we will die. Twice.
If our hearts are not right with God, we must come to the realization that we cannot fix our hearts on our own: only God can do that. It is beyond our reach to make ourselves clean enough to live in His presence forever. His Word tells us that our righteousness is like filthy rags (Isaiah 64:6).
We need to be true worshipers.
