Asa’s heart was perfect with the Lord all his days.
Another way to say this is “Asa’s heart was fully committed to the Lord all his life.” Two words really stand out in this - fully and all. Compare this to Solomon who started out well but finished in shambles. David is another example who made a very serious mistake because his commitment quit for a while. That’s the way it is with Satan. As soon as our commitment to the Lord fades, the devil’s right there with a whopping big temptation to make us trip up. Let’s make Asa’s example a motto for ourselves - to be committed to the Lord all our life.
