When St. Peter heard that Jesus was going somewhere, he wanted
to follow the Lord. Jesus refused, and told the apostle that he
would follow later. Peter protested: He was willing to lay down
his life for Jesus (again something that he ultimately would do
later). Then Jesus dropped a bombshell: That very night, Peter
would deny him three times.
The final battle to following Jesus is the battle of self. No matter
how pure our motives may seem, until we trust in God more
than we trust in ourselves, we are doomed to fail. To truly follow
Jesus, we must unite ourselves with him and trust him totally.
