Today God has given me something in Revelation 3, verses 7 through 8, which say:
“And to the angel of the church in Philadelphia write: ‘The words of the holy one, the true one, who has the key of David, who opens and no one will shut, who shuts and no one opens. “‘I know your works. Behold, I have set before you an open door, which no one is able to shut. I know that you have but little power, and yet you have kept my word and have not denied my name. (Revelation 3:7-8)
That we do good ‘works’ is not something which is required for a Christian to be saved. Good works have no part in salvation, other than to make it clear that we are indeed saved; if you don’t try stop that robber, or you walk away from a mugging, you need to seriously examine your faith. However, God does still judges our deeds… Not to determine if we’re worthy of His grace, but to see who would benefit most from having a door opened in some area of ministry for them. As He says here, “I know your works. Behold, I have set before you an open door, which no one is able to shut.”
They didn’t deny His name, and they did good in His sight, thus He rewards them with a more influential ministry. He hasn’t stopped doing that just because some time has passed, either. However, God opening a door for us doesn’t entirely hinge upon us doing good works. God loves to open doors for people to do good works, give them a little shove towards it, then reward them when they actually do those good works. However, what is important for us, is to ‘walk through the door’ when it is opened. We shouldn’t hesitate because we aren’t sure it’s in our best interests, or because we think it will take away from our free times; anything God wants us to do is always in our ‘best interests’.
Knowing if it’s God’s will for us to doing something, though, is a tad harder. That requires discernment. However, a general rule of thumb is this: if it would further God’s kingdom, it’s probably from God.
