Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need. Hebrews 4:16
The second president of the United States, John Adams (and his wife, Abigail), was the first president to occupy the White House. In his day, and for many years afterward, it was possible for average citizens to walk into the White House unannounced to attempt to see the president. Try that today! Multiple levels of security shield the president from the average citizen seeking an audience.
If it's difficult to see the president of the United States, or the leader of any modern country, think how much more difficult it ought to be to have an audience with God. But it's not difficult at all! Scripture tells us that all who have been made pure by the blood of Christ can come "boldly to the throne of grace" to "obtain mercy and find grace to help in time of need." But how many take advantage of that free access? If we don't, it's not because we don't need mercy or grace; it's not that we don't have times of need. It's more that we just can't comprehend what it means to have unfettered access to the God of the universe.
Have you entered into God's presence today? The door is open, waiting for you to walk through, if only you will.
The door is closed to prayer unless it is opened with the key of trust.
