Matthew 7:13, 14 "Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it. But small is the gate and narrow the road that leads to life, and only a few find it."
The gate is a place of death, and death is a place of separation. I have been crucified with Christ and I no longer live, but Christ lives in me. The life I live in the body, I live by faith in the Son of God, who loved me and gave himself for me (Galatians 2:20). This scripture is foundational and most descriptive of our new life in Christ. Romans 6 further clarifies the death to the old. What shall we say, then? Shall we go on sinning so that grace may increase? By no means! We died to sin; how can we live in it any longer? Or don't you know that all of us who were baptized into Christ Jesus were baptized into his death?. . . For we know that our old self was crucified with him so that the body of sin might be done away with, that we should no longer be slaves to sin--because anyone who has died has been freed from sin. . . . In the same way, count yourselves dead to sin but alive to God in Christ Jesus. Therefore do not let sin reign in your mortal body so that you obey its evil desires. Do not offer the parts of your body to sin, as instruments of wickedness, but rather offer yourselves to God, as those who have been brought from death to life; and offer the parts of your body to him as instruments of righteousness. For sin shall not be your master, because you are not under law, but under grace. . . .For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord. In one sense, we are "dead men walking." But at the same time, we are more alive than ever in the new life that Christ gives us, resurrection life! The same gate that brings death, also swings into LIFE and LIFE more abundant. We are born again as babes and then called upon to mature to experience the full rights of sons. Galatians 4:4-7 But when the time had fully come, God sent his Son, born of a woman, born under law, to redeem those under law, that we might receive the full rights of son. Because you are sons, God sent the Spirit of his Son into your hearts, the Spirit who calls out, "Abba, Father." So you are no longer a slave, but a son; and since you are a son, God has made you also an heir. God is working in us to bring forth this new life. Therefore, my dear friends, as you have always obeyed--not only in my presence, but now much more in my absence--continue to work out your salvation with fear and trembling, for it is God who works in you to will and to act according to his good purpose (Philippians 2:12, 13). We are living in the Kingdom to the degree that we yield to the work of the Spirit in us. I've heard it said that we are living in the Kingdom on the way to the Kingdom. We are becoming those sons and daughters of God even more fully as we grow in our new life every day. As we live in God, we are shedding the old and embracing the new! So we can choose to stay separated from God or we can choose to separate (by His Spirit) from those things that separate us from God. The more we see and know God, the more we want to let go of anything that keeps us away from Him.
