Back to that quote. Every time I think about it, it reminds me of our mission in life. Let's start from the top.
"Fight hard for what's right" - There is so much in life we need to fight for. We need to fight hard for personal holiness to God, we need to fight hard to humble ourselves before God, we need to fight hard for holy relationships, we need to fight hard to keep from the lusts of the flesh, and the list goes on.
How about the other half - "Hold fast to what's true" Just like we need to fight hard, we need to hold fast in life, and again, there is so much to hold fast to. We need to hold fast to the truth of God's word, we need to hold fast the the fact that God is faithful and just to forgive, if we confess our sins, we need to hold fast to the fact, that if we live our lives in submission to him, one day God will say to us "well done, my good and faithful servant, thou hast been faithful over a few things, I will make thee ruler over many things: enter into the joy of the Lord" Mat 25:21.
In fact, fighting hard for what's right, is a direct result of holding fast to what's true. If we hold fast to the fact that God is faithful and just to forgive, we will fight hard to confess our sins, to God, and to man, and the examples go on.
Finally, let it be said here, none of this is possible outside of the help of God. If it wasn't for God's saving grace, we would still be lost in our sins. If we were still lost in our sins, we would never even have the want, the will, the desire, or even the ability to submit to God, confess our sins, or be in submission to his will and word. Everything in life points back to our great God sending his son to pay the penalty for our sins, to bring us back to a right relationship with him, just because he loved us. Once again, it reminds us of our mission in life. Taking ground for the creator, in absolute gratitude and submission to him, till he calls us home.
