Notice that Jesus’ mandate is “daily”, not occasionally, or when we feel like it. Mastering anything requres daily practice. Denying ourselves in small things, tiny things, helps us develop soul strength just like lifting weights would help us develop muscle strength. We go for a walk when we don’t feel like it, we drink water instead of juice. Each tiny act of self-denial sets us free, increases our self-possession, strengthens our souls and as a result, expands our capacity to love and be loved. Jesus wants us to love and be greatly loved.
