“And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.” -Hebrews 11:6
The person who trusts that the work of his own righteousness was done and finished by Jesus when he was crucified, the person who knows he can’t add or subtract to that work in any way, who doesn’t toil to please God or try harder or crucify himself when he fails, that person finds peace. There is no other way. That is the gospel. That is all.
Will you spend your life trying to please God, or will you simply trust him?
