4. In The Beginning God
Gen 1:26 Berfirmanlah Allah: "Baiklah Kita
menjadikan manusia menurut gambar dan rupa Kita,
supaya mereka berkuasa atas ikan-ikan di laut dan
burung-burung di udara dan atas ternak dan atas
seluruh bumi dan atas segala binatang melata yang
merayap di
bumi."
Gen 1:27 Maka Allah menciptakan manusia itu
menurut gambar-Nya, menurut gambar Allah
diciptakan-Nya dia; laki-laki dan perempuan
diciptakan-Nya mereka.
(Gen 2:7) ketika itulah TUHAN Allah membentuk
manusia itu dari debu tanah dan menghembuskan
nafas hidup ke dalam hidungnya; demikianlah
manusia itu menjadi makhluk yang hidup.
Gen 1:28 Allah memberkati mereka, lalu Allah
berfirman kepada mereka: "Beranakcuculah dan
bertambah banyak; penuhilah bumi dan
taklukkanlah itu, berkuasalah atas ikan-ikan di laut
dan burung-burung di udara dan atas segala
binatang yang merayap di bumi."
5. In The Beginning
Lalu firman-Nya kepada manusia itu: "Karena engkau
mendengarkan perkataan isterimu dan memakan dari buah
pohon, yang telah Kuperintahkan kepadamu: Jangan makan
dari padanya, maka terkutuklah tanah karena engkau; dengan
bersusah payah engkau akan mencari rezekimu dari tanah
seumur hidupmu: semak duri dan rumput duri yang akan
dihasilkannya bagimu, dan tumbuh-tumbuhan di padang akan
menjadi makananmu; dengan berpeluh engkau akan mencari
makananmu, sampai engkau kembali lagi menjadi tanah, karena
dari situlah engkau diambil; sebab engkau debu dan engkau
akan kembali menjadi debu."
(Gen 3:17-19)

A SW engineer in US with 2 years experience might
make $50k per year, but there is pressure from
Employs 1.7 Million People in US in 2007 in US alone for Software & globalization. The other thing to keep in mind is the cost
related services Factor of living is much higher in the US so in some respects
your standard of living might be worse.
A beginning software engineer could earn as little as $25,000-$30,000 annually, or as much as $60,000-$70,000 in expensive areas of
California -- or potentially more for a very good graduate, or a well-paying job.
A software engineer with 5-10 years of experience will make more, often $90,000-$100,000 or more in California, up to occasionally $200,000
or more per year. In less expensive areas it's often less. In Pittsburgh, PA, for instance, assume a software engineer will make $30,000 to
$35,000 less per year at a similar job. There are also significant differences depending on the kind of company the engineer works for, and
the type of job. The job title also usually changes to something like "senior software engineer".

Sesungguhnya telah terdengar teriakan besar, karena upah yang
kamu tahan dari buruh yang telah menuai hasil ladangmu, dan telah
sampai ke telinga Tuhan semesta alam keluhan mereka yang
menyabit panenmu.
(Jam 5:4)
Tinggallah dalam rumah itu, makan dan minumlah apa yang
diberikan orang kepadamu, sebab seorang pekerja patut mendapat
upahnya. Janganlah berpindah-pindah rumah.
