16 Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in time of need.
that we may obtain [receive] mercy
Jesus is merciful toward His own. One way He does this is by interceding on our behalf (He 2:17; 8:12). “Mercy” is forgiveness of deserved judgment. Mercy, then, means that God does not give us what we deserve.
Note that the word “obtain” means receive. We do not earn or deserve the right to obtain mercy. No, we “receive” mercy from God’s grace. We do not attain but obtain God’s mercies because God is a God of grace (1 Pe 5:10).
and find grace to help
Grace is what God does for us; it is His provisions on our behalf. “Grace” is God’s provision of undeserved blessing. Grace means that God gives what we do not deserve. God gives grace to “help” us with our problems (He 2:18).
in time of need.
Whether the Christians’ need is forgiveness or help during times of duress, they can approach Jesus with this problem at the moment they need it. The word “time” means season. He knows what is suitable for our situation. God gives us only what we need according to the need itself.
Christians have confidence that God will answer their prayers.
The Christian’s approach to God should be characterized by confidence. The approach to God should be free from fear. We have courage in prayer because of our accepting the High Priest. Christians can freely express themselves in prayer. They can speak openly and freely to their Lord because He is a merciful High Priest.
This courage to pray is not our own; it is something that comes from our High Priest by His mercy and grace. We can then be frank about our needs.
There is grace to help saints. Grace is free and is given as help for the helpless (Jas 4:6). The Lord is in heaven taking care of all our affairs in heaven. We have an accessible High Priest. God knows all about our problems. He makes provision for our every need.
