Being a Christian doesn't mean being perfect. In fact, being a Christian starts with us admitting our sins, and coming to a realisation that we can't do anything to save ourselves. Being a Christian ultimately means being totally reliant on God's goodness, and wholly surrendered to Him.
Yet, in all things, we Christians feel the strain of showing Godly character. This is something that, as mere sinners saved by grace, we find hard or even impossible to do in our own strength. So, it is very reassuring to know that being a Christian doesn't mean being perfect but being perfected, not being righteous in ourselves but made righteous in Christ, and not knowing it all but merely trusting in God for everything.
Whatever you're going through, keep pressing onward to the Lord. He'll use your story as a testimony of His goodness and love.
