<p>3:10 <em>For he that would love life and see good days</em>- The &quot;good days&quot; are those of the Kingdom to come; if we love the idea of the life eternal, then we must live now as we shall eternally live. For the Gospel gives us eternal life now in that we can live now as we shall eternally live, as John's Gospel points out. Matthew tends to put it another way; the parables of the Kingdom refer to life lived now, which is the Kingdom life. The quotation here in 3:10-12 is from Ps. 34:12-16 LXX, but with variations- an example of how inspired writers quote the Old Testament but change various details to be relevant to their theme or audience.</p><p><em>Let him restrain his tongue from evil and restrain his lips so they speak no lies</em>- But how in practice to &quot;restrain&quot; the tongue? We lack the iron will to do so, in many cases. Iron will, steel in the soul, is surely not the way to spirituality. The same word is used in 4:1: &quot;Forasmuch then as Christ suffered in the flesh, arm yourselves also with the same mind. For he that has suffered in the flesh has <em>ceased</em> from sin&quot;. The Lord Jesus suffered and died. If we identify with His death, in baptism and an ongoing commitment to let His death be our pattern, then we will be counted as in Him, and will naturally seek to live according to that status. And His Spirit will help our efforts. This is the way to cease or restrain from sin, such as speaking lies. Note the parallel between &quot;evil&quot; and &quot;lies&quot;. Lying is evil. Dishonesty is at the heart of all sin.</p>
