Psalm 2:11 commands: “Worship Yahweh with reverence; rejoice with trembling.” Here we find an important balance commanded for our worship. We are to worship with “reverence” — and yet “rejoice.” We are to “rejoice” — yet “with trembling.” It reminds one of the response of the women at Jesus’ resurrection, when Matthew 28:8 says they departed with “fear and great joy.”
The balance is delicate and vital. We are not to have a “craven fear” of the Lord, but neither are we to have a joy that neglects to respect Him, and fails to walk in discipline and accountability to God. There must be both accountability and joy in a genuine, balanced relationship with the Lord.
What does this mean for us, practically?
— it means that we should strive for a balance in our worship: we should sing songs of joy, but also songs of holiness and awe.
— it also means that we should draw near to God as ”Abba” Father like Romans 8:15 describes – but we must also realize that we cannot disobey without consequences – we should still fear the discipline of a Father who loves His children too much to let them continue in unrepentant sin.

I feel this message is so very fitting for the times we live in. Thank you, brother Shawn, for reminding us that true worship of God is never without our consciousness of Who He is and who we are.
I too think it is important for our times, because often what we see is a tendency towards one extreme or the other, instead of that vital, delicate (and Biblical) balance. Thank you for your encouraging input, Marie-Anne!
