Psalm 86: 11-13
Teach me your way, Lord, that I may rely on your faithfulness; give me an undivided heart, that I may fear your name. I will praise you, Lord my God, with all my heart; I will glorify your name forever. For great is your love toward me; you have delivered me from the depths, from the realm of the dead.
Jeremiah 17: 9
The heart is deceitful above all things and beyond cure. Who can understand it?
Acts 5: 1-4
1 Now a man named Ananias, together with his wife Sapphira, also sold a piece of property. 2 With his wife’s full knowledge he kept back part of the money for himself, but brought the rest and put it at the apostles’ feet. 3 Then Peter said, “Ananias, how is it that Satan has so filled your heart that you have lied to the Holy Spirit and have kept for yourself some of the money you received for the land? 4 Didn’t it belong to you before it was sold? And after it was sold, wasn’t the money at your disposal? What made you think of doing such a thing? You have not lied just to human beings but to God.”
Colossians 3: 9-10
Do not lie to each other, since you have taken off your old self with its practices and have put on the new self, which is being renewed in knowledge in the image of its Creator.
Proverbs 15: 1
A gentle answer turns away wrath, but a harsh word stirs up anger.
