Philippians 4:13

I have strength for all things in Christ who empowers me-I am ready for anything, equal to anything through Him who infuses inner strength to me, (that is, I am self-sufficient in Christ’s sufficiency) 

The devil will try and steal from us and tell us we have to come up with all the answers to problems ourselves. We need to help God, or God is too busy to help us. Christ went away so the Holy Spirit could come inside us as be our strength and power. When we turn to Jesus and be guided by the Spirit, the answer will come.   Jesus is our sufficiency when we trust and lean on Him.
