In short some of the core of christianity are being twisted.
Some of what I learnt from the bible and my mother are as
below.
(1) It is not compulsory to give offerings, but it is
compulsory to to give with a cheerful heart.
(2) It is not only giving to church that is considered
giving. You help a begger along the streets up, clothe
him, feed him, find him a job, make him your friend, when he dies,
you settle his last moments, all in the name of Jesus. Is also a
form of giving. And never ever expect a single cent from
God or expecting to let other people know your deeds when you're
doing this. And God while seeing you do this in private
will be happy for you.
(3) When giving offerings (tithe), do not expect to reap the same
amount from God. Because it is only duty to do it. What
returns do you expect when you perform your duty.
(4) Even when you received Christ before you go and murder someone,
don't expect to escape punishments for your sins. But you
can count on God to forgive you after your
punishments.
Today there are many perversed versions of how christianity should
be. But alas, the perversed version is given so much attention to
propagande to the people that the core of Christianity is neglected
and misunderstood. And also, God's standard is always perfect. No
one in the world can even fathom that level. For all fall short to
the glory of God. Always ask and check the bible, don't always
believe everything you hear from anyone blindly. Let God lead you
to understand his ways because no man can replace God as a
teacher.
