Just then a man came up to Jesus and asked, Teacher, what good thing must I do to get eternal life? - Matthew 19:16
What the scripture is telling us today, by the story of this rich man that approached Jesus, is that there is nobody as perfect as to gain, by his own merit, however good he might be, his entrance to heaven, his ticket to eternal life.
Salvation is by no means something we get by doing something; rather, it is achieved by something Jesus already did, and the only thing that's 'left for us to do' is to simply acknowledge our own faults, our incapacity of living life as God intended us to, and humble ourselves in his presence and asking him to forgive us of all sin, then receiving his son Jesus into our hearts as Lord and Savior.
The problem is, though, from the start we are too proud to humble ourselves, to admit that someone else's paid the price for our salvation, and we keep on trying to do something to repay Jesus for his sacrifice, which is not only ineffective, insufficient, but also impossible to do, because of his holy nature, which was the only acceptable sacrifice, and something we could never match.
My prayer today is that God bless us with the understanding that we don't have to pay for his grace (which would not be called grace if we had to pay for it), that He may lead us into genuine repentance, and that He empowers us, through the Holy Spirit, to accept Jesus' sacrifice on the cross, and in so doing we become his servants, his friends, his children.
