It does not read _seeding_ and harvest. _Seeding_ means the act of
sowing seed. The Lord in his covenant does not say that this shall not
cease; because the act of sowing seed or _seeding_ depends upon man:
he only assures man that seedtime, or the time for sowing seed, shall
not cease. But notice the other part. He does not say harvest-time;
but he says that _harvest_ shall not cease, because _he makes the
harvest_. He speaks positively here of results, as being able and
forever willing to fulfill what he covenants to do. In this covenant,
man's work is implied as well as God's work. Man's part of the work is
to sow the seed when the time is given. God's part is to bless the
seed sown, by giving the harvest. In all of man's labor pertaining to
providing for the support and comfort of his body, "we are coworkers
with God."
Our heavenly Father deals with us as children. By natural things he
instructs us in spiritual things. Paul says; "First that which is
natural; afterward that which is spiritual." This is God's order.
