The Christian life is a battle. It is not some bed of roses. We have a great enemy, Satan, who will do all he can to prevent us from doing things that we should, like praying, reading God's word, meeting with other Christians to worship God and to hear His word preached. However, we have a greater Saviour. Peter wrote to Christians:
(1Pe 5:8-10 NKJV) Be sober, be vigilant; because your adversary the devil walks about like a roaring lion, seeking whom he may devour. Resist him, steadfast in the faith, knowing that the same sufferings are experienced by your brotherhood in the world.
But may the God of all grace, who called us to His eternal glory by Christ Jesus, after you have suffered a while, perfect, establish, strengthen, and settle you.
Another good passage to bear in mind is Ephesians :10-18, where Paul writes about the Christian's armour:
(Eph 6:10) Finally, my brethren, be strong in the Lord and in the power of His might.
(Eph 6:11) Put on the whole armor of God, that you may be able to stand against the wiles of the devil.
(Eph 6:12) For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.
(Eph 6:13) Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand.
(Eph 6:14) Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness,
(Eph 6:15) and having shod your feet with the preparation of the gospel of peace;
(Eph 6:16) above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one.
(Eph 6:17) And take the helmet of salvation, and the sword of the Spirit, which is the word of God;
(Eph 6:18) praying always with all prayer and supplication in the Spirit, being watchful to this end with all perseverance and supplication for all the saints—
