For if our heart condemns us, God is greater than our heart, and knows all things – I John 3:20
If you cannot forgive yourself of your shortcomings, you will be short-changing yourself of your inner peace. Guilt complex puts a damper on the spirit-man of its victims and also builds a hedge of sorrow around them.
For you to overcome your guilt, you need to:
(1) forgive yourself and seek forgiveness. This helps you to regain your inner peace, joy and acceptance by the ones you have offended
(2) feast on the word of God, to discover the truth and to re-gain the unlimited freedom therein
(3) focus on Jesus, the Author and Finish of your faith, to open a new chapter to you so you could build a renewed and profitable network with God and man.
(4) find opportunity to do good, in order to demonstrate the love of God
May the Lord weed out the guilt complex that may be hindering your peace, progress and the prosperity of your soul in Jesus name.
