I realized that to come to a personal relationship with God through Jesus Christ is to pledge to stay delighted in Him despite any situation one is in. The essence of Christianity is not to devise one's own plans, manage one's own life outside the master plan of God and beg Him to bless them; the essence of Christianity is to be in constant communion with the Father by prayer, by reading His word and by living out His truths by grace through love whatever happens. It is to bask in who God is and allow one’s self to be a channel of His work in the world. Everything else falls secondary to what God wants so bad from us – our hearts, hearts that are generally committed to a lifetime of surrender to Him, a lifetime of commitment to be driven by His guidance.
When people reject Christianity, it may be that they don't want to be intimate with this God that appears to be unsafe because of his many surprises. The Lord is an adventurous God indeed. He takes people to roller coaster rides, to mountain hikes, to bungee jumping, to SCUBA diving and the like. He does not promise safety from bruises, cuts or falls but He promises that in the end, after all the adrenaline rush, one is eternally secure.
I cannot emphasize it enough that the essence of being a Christian is the relationship itself that which should go through thick and thin, for better or for worse, for richer or poorer. Yes, like that which requires the highest commitment mandated in Marriage. When we accept Jesus in our lives, we are married to Him - forever and ever. And if it is easier to understand the love expected to manifest between a husband and wife, then that is what I mean.
