The Sin of “Self Confidence”
ByOh my goodness! How can self confidence be a sin? Well, self confidence is a sin because Jesus said we are incapable of doing anything apart from Him. The sin of self confidence is the sin of pride and an inflated ego. Self confidence from the sin perspective involves believing we are superior and better than others. Self confidence embraces an attitude of entitlement and claims to have many rights that supersede the rights of others.
My guess is than most Christians believe they have the right to be happy and that making us happy is God’s main priority. It would shock most believers to learn that such an idea can’t be supported from scripture. God is only interested in making us like Jesus and along the way He promises that we are going to suffer! It is true that mature believers eventually experience the ‘peace that passes understanding’ but that is not the kind of happiness most people pursue. They pursue happiness for the flesh. The peace of God comes only after a believer has learned they must have no confidence in their flesh.
Faith and dependence on Jesus Christ is the only basis Christians have for confidence from a Biblical perspective. If we believe we can do anything on our own we are not allowing Jesus to live His life through us. On that basis, self confidence is a serious sin and it blocks the Holy Spirit from filling us.
