Hebrews 4:15,16

For we do not have a High Priest who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin. Let us therefore come boldly to the throne of grace, that we may obtain mercy and find grace to help in the time of need.

God never intended for us to have to face this world and its temptations by ourselves. The bible gives examples of people who sinned and received grace and mercy from Him. God also says we can come boldly to the throne of grace in our time of need. Jesus is our High Priest and the key to our salvation and forgiveness of our sins and can sympathize with everything we go through.
