Only Jesus was sinless and He is without sin

"For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps: 

Who did no sin, neither was guile found in his mouth:" 1 Peter 2:21-22

"And ye know that he was manifested to take away our sins; and in him is no sin." 1 John 3:5

Repent, turn away from your evil and wicked ways and put your faith in Jesus Christ. Live holy for him because the Bible calls us to live a holy perfect life in front of Jesus. We strive for perfection in this life, even though we are not perfect and will never get there but we want to try to be. We are only forgiven of our sins by the blood of Jesus. And we are saved by God's grace. Only when we are in Heaven will we be without sin and perfect. We will have bodies just like Jesus. We will be just like Him. 

"And as we have borne the image of the earth, we shall also bear the image of the heavenly." 1 Corinthians 15:49

"Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is." 1 John 3:2
