The grace of God is not only provided to us freely, but it's expected that we will operate fully in it. As a believer, you have the kingdom of God dwelling in you by way of the Holy Spirit. All you have to do is believe!
True faith endures, regardless of what is seen in the natural. To walk by faith is to not walk primarily by natural eye-sight, but to move forward based on spiritual insight which is supernaturally revealed to the inner man by God the Father.
Remember that without faith, it is impossible to please God, but if you have faith the size of a mustard seed, you can move mountains.
What has God called you to, and what has He placed inside of you to believe for? Press In. Believe God, don't let go, and you will do great exploits to bring Him glory!
Believe in Jesus, and be amazed!
