This quotation from Isaiah 40:6-8 contrasts the transitory character of nature and the eternality of God"s Word (cf. James 1:10-11). Every natural thing eventually dies and disappears, the opposite of God"s living and abiding Word (cf. Matthew 24:35; Mark 13:31; Luke 21:33). The seed lives and abides, and so do those to whom it gives new life. [source][source][source]
"My friend, we need the preaching and the teaching of the Word of God above everything else. I do not mean to minimize the place of music, the place of methods, and the place of organization, but there is absolutely no substitute for the Word of God today." [1][source]
The duty of Christians to one another then is to love one another unremittingly. This is true even of Christians who are suffering for their commitment to follow God faithfully. We can and should do so because we are genuine brethren and because we will abide forever. [source][source][source]
