Doing the right thing doesn't always mean it's the easy thing.
Children are wonderful examples, when a child misbehaves it is right to correct their attitudes but when they're screaming like you've beat them with a baseball bat in the middle of the grocery store, it's certainly not easy to maintain a competent level of control over the situation.
We are children of God. How many times are we sitting in the middle of the candy aisle at the grocery store demanding God give us what we want? We want answers, direction, we want what we want. It might not be that we're crying or throwing a tantrum, but maybe we're just talking so much about that yummy thing and making promises to Him, if only He'd give it to us, making so much fuss about it that we missed what He said.
We don't want the healthy answers God's offering, we want the sweet treats, the yummy chocolate instead, a good choice for a snack, but we turn down the best choice. We so often choose something of a lesser quality because we don't believe God has something better. That's a trust issue. We justify ourselves by thinking things like, "Why would God have me here if it's not what He wanted for me" and miss the fact that He gave us a choice and we chose good instead of best.
Many times, God gives us choices to test our hearts. Will we choose something temporarily satisfying or will we choose what is best for the long run? Paul says to keep our eyes focused on the goal, Jesus. Anything that gets between our eyes and Jesus is something we can trip over.
If your choice today boils down to choosing what is good or what is best, pray for wisdom and discernment to know which is which and then listen to God as he speaks through His Word, the Holy Spirit, other believers, and situations. He might be asking you where your heart is on an issue.
Always choose the best thing, that's what He has waiting for you.
