Many things people say to us came from "motivational manuals." They are not only NOT in the Scriptures but against the Word.
No where in the Word does God tell us to be "proud of ourselves" or to "praise ourselves." This runs contrary to the will of God. When we obey Him, give Him the credit for the good that we have done, then we will always give Him the glory for everything.
Romans 12:1 "I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, which is your reasonable service."
James 1:22
"But be doers of the word, and not hearers only, deceiving yourselves."
So many things sound good but do not please the Lord.
Galatians 6:7-8
"Do not be deceived: God is not mocked, for whatever one sows, that will he also reap. For the one who sows to his own flesh will from the flesh reap corruption, but the one who sows to the Spirit will from the Spirit reap eternal life."
Romans 12:2
"Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect."
