The Lord gives us burdens for Him and to do His work. When we listen to the voice of God he directs us. Is your course right? Is the power of the Lord upon your life? We need pastors and Christians to follow the Lord and despites improbable odds, we will experience the growth of the Lord.
Believers are Sinners Saved. They were once the friends of the world, but are reconciled to God by the Friend of Sinners. He redeemed them and gives them his Spirit. By the Spirit of God they are regenerated and made the friends of God through faith. Just like Abraham. And this is wrought in them all by the grace of God in Christ.
Life happens, life gets in the way, life demands our attention, so what are we going to do about it? Here for whatever the reason Mark turned back. Something distracted him from his course and now he regretted being where he was.
Christ reveals in two striking statements His clear purpose, His robust conviction to pursue His purpose and a consciousness to ensure the work was finished. He is to be our pattern and example in life. We too, must glorify God and finish our course.
It's not that God is not able to save or have no power to save, but that we have distanced ourselves from Him by our sin. It is us forsaking Him, for the love of this present world. He is able and will deliver us from this present evil world when He converts us into Sons of God. We have to turn from our sins in repentance, be sanctified by His word for His power to dwell richly in us.
Though some will take longer to agree and catch up on the race of progressive sanctification, the ones who are more mature and focused should not be distracted from keeping their determined holy walk. Some less mature Christians who resist significant change will risk your spiritual growth. You must understand whether you are of more experienced, Christian maturity. And if you are mature, you will know you are never done maturing until heaven. Stay the Course of Maturity in Sanctification.
