Joshua 23 At the age of 120 Joshua told the leaders of Israel, "I am old, advanced in years." His message to them was spoken with both hope and caution. He reminded the people of all that God had done for them.. ".. the Lord your God is He who has been fighting for you."
He exhorted them to:
"Be very firm, ( strong or courageous) then, to keep and do all that is written in the book of the Law of Moses, so that you may not turn aside from it to the right hand or to the left." (v6)
"But you are to cling to ( cleave; stick close, follow closely ) the Lord your God, as you have done to this day." (v8)
"So take diligent heed ( keep, have charge of, watch and wait for, be on guard ) to yourselves to love the Lord your God." ( v11)
He warned them against associating with the nations that were still living in the land; of even speaking the name of the false gods. The nations needed to be driven out of God's land.. for they would become "a snare and a trap.. a whip on your sides and a thorns in your eyes.."
Joshua's concern for the people of Israel is deep and troubled. "When you transgress the covenant of the Lord your God.. and go serve other gods.. then the anger of the Lord will burn against you, and you shall perish quickly from off the good land which he has given you."
Joshua's message is a good word for all of us.. we also must "be very firm" in our obedience to the Lord's Word; we must also "cling to the Lord" - constantly abiding in Jesus Christ the "true Vine"; and we must also be "diligent" to love the Lord.
II Peter 1:5 reminds us of this also... "Now for this very reason also, applying all diligence, in your faith supply moral excellence, and in your moral excellence, knowledge; and in your knowledge, self-control, and in your self-control, perseverance, and in your perseverance, godliness; and in your godliness, brotherly kindness, and in your brotherly kindness, love. For if these qualities are yours and are increasing , they render you neither useless nor unfruitful in the true knowledge of our Lord Jesus Christ."
Diligence.. personal attention and care.. to guard with earnestness and eagerness; with haste.. We must apply ourselves to these exhortations.. Perhaps if the Israelites had done so - things would have turned out so much better for them.
Peter wrote "Therefore, brethren, be all the more diligent to make certain about His calling and choosing you; for as long as you practice these things, you will never stumble; for in this way the entrance into the eternal kingdom of our Lord and Savior Jesus Christ will be abundantly supplied to you." (v10-11)
Father in heaven, You have granted to us Your precious promises so that we can partake of Your divine nature, for in Christ Jesus we have been made one with You. How great is Your salvation! Help us by Your indwelling Spirit to be diligent in clinging to You, standing firm in faith, and loving You more and more every day and every hour. We ask this in the Name of Jesus our King, Amen.
