Often do I interact with various people. They're all at different stages of life as am I. The one thing that ties each interaction together under a common banner is that of love. Loving people where they're at and not caring where they go--or telling them where to go. Even in mind does this paradigm work. If I entertain a thought of carelessness it will surely show in my eyes. Forget body language and all that, if someone looks in your eyes and doesn't like what they see, it doesn't matter how you're standing.
"O how I love Thy law! It is my meditation all the day." (Psalm 119:97)
"Great peace have they which love Thy law: and nothing shall offend them." (Psalm 119:165)
This idea of offense. Even that. Sentence fragments. As much as I love to run roughshod over the mores of English--because I know how it works--and play around, it doesn't mean someone reading (and in the case of my life, watching) will get my intended meaning. The heart behind the words as it were. It is very easy to offend someone or to get offended ourselves. God would have us forgive our offenders. As much as we "love God's law", we need to realize God's never done with us. The lessons of forgiveness and not holding against any person the slights they level at us in word or thought will come back around. If all we want is to see someone become a "Christian"--i.e. "saved"--and we're not willing to do our best with the instance of interaction we do get (because the high privilege of leading someone to the Lord is God's to deal as He will), it may well hamper their entry to the Kingdom of Heaven. Paul writes to the Romans (7:22-23) "For I delight in the law of God after the inward man: But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members." In other words, He "loves God's law" as David does from Psalm 119. But inevitably--as I find and am finding--the other gears on our insides, ones that turn an opposite direction to God's thoughts, will seek to make their way into the machinery. And gears will only mesh one way, and one way only. We have a new heart upon believing in Jesus. It's our minds that have to catch up.
