The attitude of ungratefulness irritates God. Where I come from in the western part of Nigeria, our people would say, "Don't follow-up your benevolent act so that you don't give the impression that you want a 'thank you' or some 'hero worship'." This saying is very correct because only God deserves our worship. As a matter of fact, it is only God that is capable of constantly following up His benevolent act and that is why He said;
"...When ye be come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring a sheaf of the fruits of your harvest unto the priest: And he shall wave the sheaf before the Lord, to be accepted for you..." Leviticus 23:10-11

Love is reciprocal. The question is how many people reciprocate the love being showered on them by fellow humans, not to talk of their attitude to God's benevolent acts. The Psalmist saw the danger in the act of ingratitude and preached vehemently to his soul when he wrote:
"Bless the Lord, O my soul: and all that is within me, bless his holy name. Bless the Lord O my soul, and forget not all his benefits:" Psalms 103:1-2

The story in Luke 17:11-19 confirms that God expects us to appreciate Him sufficiently for His goodness. Our Lord Jesus Christ queried in Luke 17:17:
"...Were there not ten cleansed? But where are the nine?"

He went further to bless and perfect the healing of the grateful Samaritan. It is unfortunate that many children of God are already so used to the miraculous acts of God that they are no longer moved by these acts. New comers into the Church who still remember clearly what they have suffered by the hands of the devil and his cohorts give thanks to God for every miracle. Whereas, some people don't give testimonies of how God healed them of headache because they don't see it as a "big deal". Such people have forgotten that the headache they consider as ordinary has claimed the lives of thousands. My prayer for someone reading this devotional is that you will never be ungrateful again in Jesus' name. When you continue in your sins after you have been cleansed of them or when you backslide, you are ungrateful to God who gave His son as ransom for your sins and to Jesus Christ who paid the supreme price of laying down His life for you. When you don't forgive your brother who offends you, you are ungrateful to God who pardoned your numerous sins. Written by Pastor E.A. Adeboye.
