Romans 13.11-14 Proper Behavior

Do this, knowing the time, that it is already the hour for you to awaken from sleep; for now salvation is nearer to us than when we believed. The night is almost gone, and the day is near. Therefore let us lay aside the deeds of darkness and put on the armor of light. Let us behave properly as in the day, not in carousing and drunkenness, not in sexual promiscuity and sensuality, not in strife and jealousy. But put on the Lord Jesus Christ, and make no provision for the flesh in regard to its lusts.
Romans 13:11‭-‬14 NASB

The Christian life is full of hope. We hope to spend an eternity with God in Heaven. We hope that we will live to see Jesus return and gather us to Himself. "But in those days, after that tribulation, the sun will be darkened  and the moon will not give its light, and the stars will be falling from heaven, and the powers that are in the heavens will be shaken. Then they will see the  son of man coming in clouds with great power and glory. And then He will send forth the angels, and will gather together His elect from the four winds, from the farthest end of the earth to the farthest end of heaven." [Mark 13:24-27]. 

And if we die before His return, we hope to be resurrected into a new body. "Behold, I tell you a mystery; we will not all sleep, but we will all be changed, in a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised imperishable, and we will be changed. [1 Corinthian 15:51-52]."

This hope should serve to keep us alert, and focused on behaving as we should.

The way to overcome sin is: don't try to overcome sin. Any effort on your part to overcome the flesh, is itself an act of the flesh. The more you focus on overcoming sin, the more you think about the sin, and the more likely you are to stumble.

To lay aside the deeds of darkness, put on the armor of light. Just as light dispels darkness, so the Holy Spirit will dispel the works of the flesh.

Put another way, "put on the the Lord Jesus Christ, and make no provision for the flesh." Jesus is our armor of light.

Jesus said, "Abide in Me, and I in you. As the branch cannot bear fruit of itself unless it abides in the vine, so neither can you unless you abide in Me." [John 15:4]. 

Abiding in Christ is not praying in the morning, doing a devotional, and then going about your day. It means to take up residence with Him. Jesus said, "Abide in me, and I in you." When we are saved, we are promised that His Spirit will dwell inside of us. Jesus abides in you. He doesn't come and go. He doesn't check in on you once in a while. He is always there, and He is always aware of you.

In the same way, we need to abide in Christ. We need to give Him our attention all day long, every day, no matter what we are doing. We need to always be aware of Him; always turning our mind towards Him. That is what it means to abide in Him. When you abide in Him, you are walking in the Spirit.

Don't think that it is too hard. It takes practice. If you get distracted, there is no condemnation, just turn your mind back to Him. If you keep at it, you will form a habit of being aware of God at all times.

This is what it means to "put on the Lord Jesus Christ". He is our armor against the darkness. He will overcome the deeds of the flesh in you, if you let Him.
