Everything that is opposed to God is
sin. This refers to all sins, including the original sin and trespasses
that we commit throughout our whole lives.
Sin is 'hamartia' in Greek.
And its verbal form is 'hamartano,' which means 'to miss
the mark.' Hence, one of the most serious sins is to incorrectly
believe in Jesus, and thus lack the ability to be saved. To neither
know nor believe in the truth is to commit the sin of disobedience
and to blaspheme against God.
If we truly do not want to commit such
a sin before God, we have to understand His words correctly and
realize the truth that Jesus has become our Savior.
We should believe in the baptism of
Jesus and His Cross through the words of God. It is a sin not to
accept the Word of God, to deviate from the truth, and to believe
in false theories.
The Bible tells us that the most serious
sin, 'the sin leading to death' (1 John 5:16), is not to believe
that God washed away all the sins of the world. We have to believe
in the birth of Jesus, in His washing away of sin through His baptism,
and in giving us life with His blood on the Cross. It is a sin if
one does not believe in the written words that Jesus was baptized,
died on the Cross and was resurrected to free us from all our sins.
