When someone speaks about self or what they have done, or will do. God's chosen blood bought people talk about Christ and what he has done for us, not what we do for him. We can and do give all the praise to him. If your not praising him who are you praising?
Matthew 18:3
And said: Amen I say to you, unless you be converted, and become as little children, you shall not enter into the kingdom of heaven.
