Purchased. As in, Jesus bought us. I found immense comfort in that idea. But let's back up for a second.
What does it mean to buy something? You trade your money for the thing you want. Let's make it more personal. I go into Nordstrom Rack. I see a pair of boots I love. I fork over the cash and they are mine. I walk out of the store. Can the store clerk, or even the owner, chase me down and say, "Give me back those boots?" No. I bought them. They are belong to me; I have a receipt for proof. They have been purchased and cannot be taken away from me.
The same with our souls, if we belong to Jesus. He purchased us with the currency of His own blood. We belong to Him and no power in heaven or on earth can take us away from Him. Even the depths of our own sin cannot separate us. And for many of us, isn't that the thing we fear the most? We think, "Oh, but I've been so bad. I've not obeyed. I've not honored Him. I have MESSED UP." Even our sin cannot take us away from Him, my friends. Our lives are hid in Him, hidden well away and impossible to steal from Him. Rest in this assurance. He knows you, He sees you, He longs for you.
For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, nor height nor depth, nor anything else in all creation can separate us from the love of God that is in Christ Jesus our Lord. (Romans 8:38, 39)
