Bring your petitions before the Lord with clean hands:

“… let him refrain his tongue from evil, and his lips from speaking deceit. Let him turn away from evil and do good; let him seek peace and pursue it. For the eyes of the Lord are on the righteous, and His ears are open to their prayers; but the face of the Lord is against those who do evil.” (1 Peter 3:10b-12 NKJV)

Analyze your life in the light of God’s Word, bring everything under His subjection in repentance and aim to lead a holy life with His help.
