How do I get ready and stay ready for Jesus' return?

Repent of sin, invite Jesus into your heart. Accept Him as Lord and Master of your life. Stop serving yourself and obey the words of Jesus. Be baptized in the name of the Father, the Son and the Holy Ghost.
Get into a relationship with Jesus. Pray and listen to His Spirit speaking in your heart. Live holy, remove all obstacles from your life that come between you and Jesus and cause you to sin.
Change your way of living. Let your whole life center around Jesus and pleasing Him.
Witness for Jesus. If you do not witness you are useless for the kingdom of heaven.
Constantly focus on Jesus in prayer at all times of the day and night always, and Jesus will reveal Himself to you.
Pray always, expect Jesus and He will put His thoughts into your mind.
Never let up one day, follow Jesus every day of your life.

How can I strengthen my love for Christ and God?

Jesus said:"Why do you call Me, 'Lord, Lord,' and do not do what I say?" Luke 6:46 and also: "If you love Me, you will keep My commandments." John 14:15.
We demonstrate our love to Jesus through our obedience to His words. Obedience to Jesus carries a high price. If we obey Him we will be rejected, scorned, mocked, persecuted and even killed. The strength and increase of love comes through the endurance. As we endure, even in the face of difficulty, our love for Jesus will increase.
