Loving others always costs us something and requires effort. And you have to decide to do it on purpose. You can't wait for a feeling to motivate you.
Grace is the power of the Holy Spirit coming to us free of charge to enable you to do with ease what you could never do on your own with any amount of struggle and effort.
There is absolutely no power in our human effort to live holy. It is only by His grace. And the result of receiving grace is we get better at living like Christ, which is something we all want, right?
It's so easy to settle for less than God's best for us because we don't always feel like taking responsibility for our behavior or putting forth some effort to do what we need to do so we can accomplish great things for God and help people. But the cost of settling for less is actually harder than being completely obedient to God's will.
There are many things that happen every day that we could murmur about if we let ourselves go there. But they really aren't worth the effort it takes to get upset and gripe about it.
