Interesting that Jesus said that the whole law was based on these two. That means that if you broke God's law you contravened either one or both of those commandments.
So how do we show love for God that involves everything that we do and everything we are? It doesn't mean being fanatical, it just needs a pause to stop and ask ourselves how God would view a decision or action that we are about to undertake. It becomes a modifier of our thought processes because thoughts almost always precede actions.
James 1:13-15 shows the chain reaction that takes place before we sin.
"When under trial, let no one say: “I am being tried by God.” For with evil things God cannot be tried, nor does he himself try anyone. 14 But each one is tried by being drawn out and enticed by his own desire. 15 Then the desire, when it has become fertile, gives birth to sin; in turn sin, when it has been carried out, brings forth death."
So if this is the process that leads to sin, love of God will prevent us from taking the first step....like blaming God or refusing to see that our own actions were at fault? We will evaluate everything from God's perspective, first.
As imperfect people, we will never be able to do anything perfectly, but we have all the advice we need to keep trying.
To an outside observer, we should be calm and rational people who love to help others. Love of neighbor should be obvious in how we interact with people whom we see in need. It would demonstrate itself by offering a helping hand "up" rather than just a hand "out".
It means not keeping company with people who are of questionable character or who use foul language or who treat God's laws with contempt. Seeking the company of like minded individuals will help us to stay "unspotted by the world".
James goes on to say....vs 19-27
"Know this, my beloved brothers: Everyone must be quick to listen, slow to speak, slow to anger, 20 for man’s anger does not bring about God’s righteousness. 21 Therefore, put away all filthiness and every trace of badness, and accept with mildness the implanting of the word that is able to save you.
22 However, become doers of the word and not hearers only, deceiving yourselves with false reasoning. 23 For if anyone is a hearer of the word and not a doer, this one is like a man looking at his own face in a mirror. 24 For he looks at himself, and he goes away and immediately forgets what sort of person he is. 25 But the one who peers into the perfect law that belongs to freedom and continues in it has become, not a forgetful hearer, but a doer of the work; and he will be happy in what he does.
26 If any man thinks he is a worshipper of God but does not keep a tight rein on his tongue, he is deceiving his own heart, and his worship is futile. 27 The form of worship that is clean and undefiled from the standpoint of our God and Father is this: to look after orphans and widows in their tribulation, and to keep oneself without spot from the world."
Who could have said it better?
