Whenever you are doing what God has called you to do, it is important to rely on His strength, His grace, and His power to complete your task. You will become frustrated if you try to make things happen on your own strength instead of relying on God. God is the author and finisher of His plans (Hebrews 12:2), and you must not try to take the place of God if you expect things to work out.
In Colossians 1:26-27, Paul reveals a mystery that has been kept hidden for ages and generations... Christ in you, the hope of glory. In other words, there is something that people of the past didn't know—it was hidden from them, a mystery to them—but Paul is now revealing that mystery to us: Christ lives in all who believe in Him! No longer is God just with his people—God now lives in his people!
Also, note that it is Christ in you that's the hope of glory—not Christ and you.
Paul then continues by saying that he labors and works for the gospel, but all of his labor is really done by Christ's power, which so powerfully works in [him] (Colossians 1:29).
If you're trying to labor without Christ's power at work within you, then your labor will be frustrating and in vain. You need to stop trying, and start dying to self so that you may be alive to Christ's power.
Struggle and frustration occur when you try to do God's job by your own strength—rather than relying on Christ's strength, which is at work in you.
Eliminate everything unnecessary in your life in order to put first things first.
1 John 5:21 says, Dear children, keep yourselves from idols. The Amplified Bible elaborates on this: Little children, keep yourselves from idols (false gods)--[from anything and everything that would occupy the place in your heart due to God, from any sort of substitute for Him that would take first place in your life]. (AMP)
It is imperative that you prevent any sort of substitute from becoming first place in your life. Fill your life with the true, living God, not a phony substitute.
You can tell what is important to you simply by examining how you spend your time. If you are spending so much time trying to make money that you don't spend any quality time with God, then wealth is more important to you than God. Likewise, if you are always spending time with friends and don't have any time to spend with God, then your social life is more important to you than God.
How you use your time is so important, because you can either invest it or waste it. However, if you waste your time, you'll never get it back. On the other hand, if you invest your time into forming a deep, close, personal relationship with God, then you will reap the rewards of such an investment for the rest of eternity.
Decide to put God first in your life: spend significant, quality, personal time with Him. Put the first, most important thing (God) first place in your life.
