Just because someone says they are a follower of God, does not mean they truly are. If they are a follower of God, God will be at the centre of all they do. They will not seek to promote themselves or be praised for their actions, as they will do everything to honour God, not themselves.
Which are you – the one who does all for God, or the one seeking self-interest or promotion?
I for one, know I try to do everything for God, but I’m not perfect, so I do fail sometimes and so can find myself doing things for me rather than for God. I simply pray that God will help me to make Him the centre of all I say and do, so that I become a true follower who always puts Him first.
