"Now I would not have you ignorant, brethren, that oftentimes I purposed to come unto you, (but was let hitherto,) that I might have some fruit among you also, even as among other Gentiles." (Romans 1:13, emphasis mine)
Paul's letter to the Romans was written later than most (not sure the order), hence the reference to wanting to reestablish contact. Paul says he wanted to come visit, but was "let". In other words, he was kept from going--for whatever reason. The two words "let" and "let" mean the opposite. Let's delve a bit deeper, shall we? What does this look like in my life?
"And Peter answered Him and said, Lord, if it be Thou, bid me come unto Thee on the water. And He said Come." (Matthew 14:28-29a)
There's so much that God wants us to do. But when we wrap our minds around the fact that He's perfect and alongside that know that all we want to do is please Him, our options tend to become limited, our focus myopic. At least this is my experience. Jesus walked across the waves (because He's perfect) to meet the disciples. Something I don't think is even echoed in the myths that predate Christianity. I digress. But this! This surely hadn't been seen before and so Peter wants to partake. Jesus agrees with a word. He let him. Peter was up to the newfound task of getting out of the boat (that in itself takes guts) and setting foot on water. I suppose it should be noted that He was going to walk to Jesus. This, as I write, plays in to my ultimate point.
"All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not." (1 Corinthians 10:23)
"All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any." (1 Corinthians 6:12)
Paul elucidates the profound freedom found in Christ. In much the same way Jesus enables Peter to walk out to Him, Paul says he has the same freedom to live his own life. The two things he cites as hindrances in the grand scheme of things would be the doing of things that "edify not" and the doing of things that cause me to be subservient to others in a way that God wouldn't ordain. Nothing wrong with being a servant. Being manipulated into such is a different thing altogether. Think about the two polarities. God will let you do whatever you want, so long as it leads to Jesus. Think about it. One cannot live in this freedom unless they truly meet Jesus and continue to develop the relationship. I find that as I walk and live, day-in, day-out, the tasks and events and excursions on my horizon interlock into what looks to be in retrospect, the perfect will of God. And it's there He works in miracles and spontaneity and all-around fun-factor.
"And whatsoever ye do in word or deed, do all in the name of the Lord Jesus, giving thanks to God and the Father by Him." (Colossians 3:17)
God has a perfect will. But it includes all your whims and wants and random rabbit trails you might think at first glance don't line up with the former.
