Whatever God has called you to do (wife, marriage, homeschooling, ministry), He is faithful to give you the strength, power and the time to do it.  We need to constantly remember to be obedient to the areas where His will is clear and seek after His will, trusting that He will take care of the details.  Here's just a sampling of the promises scripture gives us of this:

Cast your cares on the Lord and He will sustain you; He will never let the righteous fall.  Ps 55:22

Listen to me, O house of Jacob, all you who remain in the house of Israel, you whom I have upheld since you were conceived, and have carried since your birth.  Even to your old age and gray hairs I am He, I am He who will sustain you.  I have made you and I will carry you; I will sustain you and I will rescue you.  Is 46:3-4

So then, brothers, stand firm and hold to the teachings we passed on to you, whether by word of mouth or by letter.  May our Lord Jesus Christ Himself and God our Father, who loved us and by His grace gave us eternal encouragement and good hope, encourage your hearts and strengthen you in every good deed and word. 2 Thess 2:15-17

Because of the Lord's great love we are not consumed, for His compassions never fail.  They are new every morning; great is Your faithfulness.  I say to myself, "The Lord is my portion; therefore I will wait for Him."  The Lord is good to those whose hope is in Him, to the one who seeks Him; it is good to wait quietly for the salvation of the Lord." Lam 3:22-26
