“Only by grace can we enter,
Only by grace can we stand
Not by our human endeavor, 
But by the blood of the Lamb.
Into Your presence You call us;
You call us to come.
Into Your presence You draw us,
Now by Your grace we come.”

As the song states, it is only by the grace of God that we can enter into His presence.
“For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not of works, lest anyone should boast.”  Ephesians 2:8-9

“Not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit, whom He poured out on us abundantly through Jesus Christ our Savior.”  Titus 3:5-6

We enter by the blood of Jesus Christ who is the Lamb slain from the foundation of the world:
“The next day he (John the Baptist) saw Jesus coming to him, and said,
‘Behold, the Lamb of God who takes away the sin of the world!’”  John 1:29

1John 3:35 tells us, 
“And you know that He appeared in order to take away sins; and in Him there is no sin.”

He (God) made Him who knew no sin to be sin on our behalf, that we might become the righteousness of God in Him.”  2 Corinthians 5:21

“But He was wounded for our transgressions,
He was crushed for our iniquities;
The chastisement for our peace was upon Him,
And by His stripes we are healed.”  Isaiah 53:5

What an awesome thing it is to enter into the presence of the Living God!
What it cost is beyond the understanding of the finite mind.  We read of the physical suffering that Jesus bore that is beyond comprehension, but worst was the spiritual suffering--taking on all sin to the point of becoming sin itself.

The crucifixion was so terrible a scene that in God’s love He covered it with darkness:
“And it was about the sixth hour, and darkness fell over the whole land until the ninth hour, the sun being obscured; and the veil of the temple was torn in two.”  Luke 23:44-45

As beloved children of God with grateful and thankful hearts let us let us praise, honor and glorify our Mighty God: Father, Son and Holy Spirit.  This is, after all, our reasonable service!

“I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service.”  Romans 12:1
Amen
