New International Version:

The horse is made ready for the day of battle, but victory rests with the LORD.
New Living Translation

The horse is prepared for the day of battle, but the victory belongs to the LORD.
English Standard Version

The horse is made ready for the day of battle, but the victory belongs to the LORD.
New American Standard Bible

The horse is prepared for the day of battle, But victory belongs to the LORD.
King James Bible

The horse is prepared against the day of battle: but safety is of the LORD.
Foolish Christians, who want to demean the EFFORTS OF MAN, talk and preach interpreting the above verse to mean as below:
EVEN IF YOU PREPARE THE HORSE FOR THE BATTLE, VICTORY SHOULD COME FROM THE LORD, with an implied message that there is no point in preparing the horse for the battle when you have not secured the approval of the Lord, therefore spend 7 days in church activities and please the Lord.

They steal the labour of man for 6 days a week to please the Lord. Thereafter, when success has gone to the Church and its trust funds, and  the man has aged, he is told to keep praying for his sons and grandchildren! The Churches make you old with assurances purveyed through Hope.

Whereas, the wiser interpretation would have been that there are two parts to Victory, one is the horse being readied by man and the second part being that the Lord should be given all glory for the Victory which ensued because of the effort of man. Man should not take, rather not appropriate the Glory of the Victory to himself, he should ascribe the victory to the Lord.

But Organisational Christianity has from the time of Pauline epistles to pagans, has  used this verse, not for egging man to redouble his efforts, but to undermine the part of man and thus stymie him and enrich the Organisation!
Luke 19:

39. And some of the Pharisees from among the multitude said unto him, Master, rebuke thy disciples.

40. And he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out.

God has unimaginable alternatives, that is not for Man to look into. Man has to DO! Pharisees did not die for the Christians, they are still interested in building the organisation by exhorting man to undermine his own efforts, so that such labour could be perennially tagged to the Organisation; and secondly, it could be obtained for free, if it is episcopally stamped as ‘Worthless’!

Innocent & fearful Christians heed these exhortations by these misinterpreting rascals, to render unto these Organisations free labour in the name of God. These Trustees of Christian organisations have thus accumulated wealth for  these Christian Organisations which have specialised in writing expense accounts and selling Organisational properties after effortless acquisitions!

Tell the foolish Christians:

GO AND PREPARE THE HORSE FOR THE BATTLE SIX DAYS A WEEK, THE SEVENTH DAY IS THE LORD’S!  

Go make your 5 talents to 10; or your 2 to 4! Don’t be like the son who pleased his father with Words, but went not to the vineyard to WORK.
