Yes, there are times we mess up and we need to repent and try again, but there are quite a few people out there that don't really realize that "Holiness" is what we are called to as part of God's Kingdom.
I hear praise songs often that are more focused on "woe, woe, woe is me!" than on anything that leads you to recognize God's glory and holiness. I think of the hymn, "It Is Well With My Soul" and compare it to hymns these days and they come up pretty short. The hymn writer wrote these words after a terrible tragedy in his life~
When peace like a river, attendeth my way,
When sorrows like sea billows roll;Whatever my lot, Thou hast taught me to know
It is well, it is well, with my soul.
He didn't focus on his hardships, he focused on God's goodness. I believe when we are growing in the holiness that we are called to then this is the same attitude that we will reflect to the world. Maybe that's why God has called us to be Holy as He is? Maybe it's His love that has called us to be Holy?
but like the Holy One who called you, be holy yourselves also in all your behavior, because it is written: 'You shall be Holy, for I am Holy." 1 Peter 1:15-16
Pursue peace with all people, and the holiness without which no one will see the Lord. Hebrews 12:14
