Do not fall for Satan’s trap of unforgiveness after someone offends you. This is one of the most common ways you fall into sin that hinders your prayers.
“Another reason I wrote you was to see if you would stand the test and be obedient in everything… in order that Satan might not outwit us. For we are not unaware of his schemes.”2 Cor 2:9-11 NIV
“Be alert and of sober mind. Your enemy the devil prowls around like a roaring lion looking for someone to devour. Resist him, standing firm in the faith, because you know that the family of believers throughout the world is undergoing the same kind of sufferings.
And the God of all grace, who called you to his eternal glory in Christ, after you have suffered a little while, will himself restore you and make you strong, firm and steadfast.” 1 Peter 5:5, 8-10 NIV
