"You can't...you can't do...you can't be...I just
can't..."
Do these words sound familiar? As imperfect human beings, we tend to say and believe these words because we wrongly limit ourselves and other people.
Yet, you can't turns into you can when you remember that if God calls you to do or be something, He will equip you for it, even if other people believe that you can't. God has equipped you with His power-the Holy Spirit-to do and be what He wants.
This is one reason why God gave us the Holy Spirit, to empower us to do what we can not do by ourselves. For the you can't mentality, remember what God's Word boldly declares you can do by the power of His Spirit:
"[You] can do all things through Christ who strengthens [you]." Philippians 4:13.
"With God all things are possible." Matthew 19:26.
"'Not by might nor by [man's] power, but by My Spirit,' says the Lord of hosts." Zechariah 4:6.
Therefore...
