Jude 24

Now to Him who is able to keep you from stumbling or falling into sin, and to present you unblemished in the presence of His glory with triumphant joy and unspeakable delight, to the only God our Savior, through Jesus Christ our Lord, be glory, majesty, dominion, and power, before all time and now and forever. 

God is more than able to keep us from falling into sin as we remain faithful to Him. The world offers shallow promises, and God offers us eternity with Him. The world may be turned on its head by evil works, but God will make the crooked ways straight for us. Do not give up or be discouraged; just believe!
