Yes, it is important to have inner peace. Sometimes, God delays to answer our prayers because He is working in us or to the other.
As we commit everything to Him - love life, relationships, family, work, everything, it always flow in our hearts an inner peace and it need not to worry. It is important to consistently pray for guidance because we face many challenges in life everyday. Making a RIGHT decision in life, would not be easy, and may take time, but with prayers and ask for His guidance, we are safe. We can know His guidance through the word of God. So it is important to read. I read Proverbs 18 today. It reminds me about about destruction and honor. In verse 12, reads, Before destruction the heart of man is haughty, and before honor is humility.
