Why do we have boldness to enter before God at any time?
The blood of Jesus!
The previous verse explains what Jesus' blood did for us: taking away all our sins. All of them.
Now, when we read this verse and take in the message about coming to God, we can understand why many people have a hard time coming to Him.
Some of us may feel that He is not big enough:
"Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure:" (Isaiah 46: 10)
Some of us may feel that He does not want to help us, because of our sins.
Regarding the guilt of our sins, some have read this passage, perhaps:
"1Behold, the LORD'S hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear:
2But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear." (Isaiah 59: 1-2)
Yet that is no longer the case, for He remembers our sins no more (Hebrews 8: 12), and:
"But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ." (Ephesians 2: 13)
"21And you, that were sometime alienated and enemies in your mind by wicked works, yet now hath he reconciled 22In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight." (Colossians 1: 21-22)
Maybe you think that He does not care about what you are going through. Perhaps you had parents who did not care what you were going through.
Jesus knows what you are going through:
"For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin." (Hebrews 4: 15)
And He cares:
"6Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time: 7Casting all your care upon him; for he careth for you." (1 Peter 5: 6-7)
Because of Jesus, all He has done and all that He is, we can come to God:
"Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need." (Hebrews 4: 16)
