The simple answer is that Jesus never said life on planet earth was going to get “easier” after professing our faith in Him. However…..

When we profess faith in Christ, “God moves in” and unleashes metaphysical power within us. Read on….

“When we come to faith in Christ, we become liberated prisoners of war. However, the battle is not over; we just changed sides. A new battle begins within us – the battle between what the Bible calls the flesh (our natural desire to sin), and the Holy Spirit who now dwells within us. Our former master, Satan, the enemy of our souls, (using our flesh as a sort of ‘base camp’) tries to apply and enforce bogus fugitive slave-laws to reclaim our mental and emotional allegiance….But, God has equipped us for overwhelming victory (Rom. 8:37). God’s greatest demonstration of His power was in the resurrection, ascension, and exaltation of His Son. We share in that power because we were raised with Christ, seated with Him, and now rule with Him (Gal. 2:20; Eph. 1:16-23). We lack nothing (Philipp. 4:13)….We cannot exaggerate the power of Christ’s person and work. Christ has triumphed over the [satanic] principalities and powers (Col. 2:15). He has rendered Satan powerless (Heb. 2:14). Because we are in union with Him, we share His victory (Eph. 2:6). That union is demonstrated by our deliverance from the dominion of darkness (Acts 26:18; Col. 1:13). Our union with Christ also means that He dwells IN US by His Spirit, and we dwell with Him (Rom. 8:9). We are now a Holy Habitation (a living, breathing temple) of the Holy Spirit (1 Cor. 6:19-20).”  (Brian Borgman & Rob Ventura; Spiritual Warfare: A Biblical and Balanced Perspective)
