Sincerity is Essential for a Successful Walk with God.

2:17 You have wearied the Lord with your words. But you say, “How have we wearied him?” By saying, “Everyone who does evil is good in the sight of the Lord, and he delights in them.” Or by asking, “Where is the God of justice?”

-For Society’s Grandeur

-For God’s Glory

B. Problem in their Heart for their Spouse

2:13-14 And this second thing you do. You cover the Lord's altar with tears, with weeping and groaning because he no longer regards the offering or accepts it with favor from your hand. 14 But you say, “Why does he not?” Because the Lord was witness between you and the wife of your youth, to whom you have been faithless, though she is your companion and your wife by covenant.

Mark 10:5-9 And Jesus said to them, “Because of your hardness of heart he wrote you this commandment. 6 But from the beginning of creation, ‘God made them male and female.’ 7 ‘Therefore a man shall leave his father and mother and hold fast to his wife, 8 and the two shall become one flesh.’ So they are no longer two but one flesh. 9 What therefore God has joined together, let not man separate.”

C. For when you’ve done your best.

Yet you rob me. “But you ask, ‘How are we robbing you?’ “In tithes and offerings. 9 You are under a curse—your whole nation—because you are robbing me. 10 Bring the whole tithe into the storehouse, so that there may be food in my house. Test me in this,” says the Lord Almighty, “and see if I will not throw open the floodgates of heaven and pour out so much blessing that there will not be room enough to store it.
