According to the Bible, Satan and his demons look to destroy the work of God and deceive anyone they can...and yes, that includes people that go to church! (1 Peter 5:8; 2 Corinthians 11:14-15).
Luke 18:10-14: Two men went up into the temple to pray, one a Pharisee and the other a tax collector. The Pharisee stood and was praying this to himself: ‘God, I thank You that I am not like other people: swindlers, unjust, adulterers, or even like this tax collector. I fast twice a week; I pay tithes of all that I get.’ But the tax collector, standing some distance away, was even unwilling to lift up his eyes to heaven, but was beating his breast, saying, ‘God, be merciful to me, the sinner!’ I tell you, this man went to his house justified rather than the other; for everyone who exalts himself will be humbled, but he who humbles himself will be exalted.
Do not be like the Pharisees who multiplied regulations, creating their own form of “godliness.” They got so wrapped up in their own rules that they lost sight of Me. (Jesus) Even today, man-made rules about how to live the Christian life enslave many people. Their focus is on their performance, rather than Me. (Jesus) (Sarah Young, Jesus Calling June 2)
Father God, please be merciful to me, a sinner! I do not have it all together, but You do. I trust You to help me live a life that is pleasing to You. I know I can’t keep the Law, but Your Son came to make it right between You and me. For eternity, I will thank You for your Sacrifice of Love through Jesus Christ. Amen.
But Martha was distracted by all the preparations that had to be made. She came to him and asked, “Lord, don’t you care that my sister has left me to do the work by myself? Tell her to help me!” “Martha, Martha,” the Lord answered, “you are worried and upset about many things, but few things are needed—or indeed only one. Mary has chosen what is better, and it will not be taken away from her.” (Luke 10:40-42)
